Overview
Composition and Structure
The Nigerian National Assembly delegation from Ogun State consists of three senators and nine members of the House of Representatives.[1][2] This structure reflects the bicameral composition of the National Assembly under the 1999 Constitution, with the Senate providing equal state representation and the House apportioning seats based on delimited federal constituencies approximating population equality.[6] The Senate component includes one senator per senatorial district: Ogun Central, Ogun East, and Ogun West.[1] These districts group the state's 20 local government areas (LGAs) as follows—Ogun Central encompasses Abeokuta North, Abeokuta South, Ewekoro, Ifo, Obafemi Owode, and Odeda LGAs; Ogun East covers Ijebu East, Ijebu North, Ijebu North-East, Ijebu-Ode, Odogbolu, Ogun Waterside, Remo North, and Sagamu LGAs; and Ogun West includes Ado-Odo/Ota, Imeko-Afon, Ipokia, Yewa North, and Yewa South LGAs—per delineations by the Independent National Electoral Commission (INEC).[9] Senators serve four-year terms, with elections held concurrently nationwide every four years.[6] The House of Representatives seats correspond to nine federal constituencies, each electing one member via first-past-the-post voting in general elections.[3] These constituencies aggregate LGAs or portions thereof to balance representation, such as Ijebu-Ode/Odogbolu/Ijebu North-East and Ogun Waterside, with boundaries periodically reviewed by INEC to reflect demographic shifts.[10] House members also serve four-year terms aligned with Senate elections.[3]Electoral Districts and Processes
The Nigerian National Assembly delegation from Ogun State comprises three senators, one elected from each of the state's three senatorial districts—Ogun Central, Ogun East, and Ogun West—and nine members of the House of Representatives, one from each federal constituency.[11] These districts and constituencies are delineated by the Independent National Electoral Commission (INEC) based on local government areas to ensure equitable representation, with boundaries periodically reviewed under the Constitution.[12] The federal constituencies in Ogun State are: Abeokuta North/Odeda, Abeokuta South/Obantoko, Ado-Odo/Ota, Egbado North/Egbado South, Ifo/Ewekoro, Ijebu Central, Ijebu East/Ijebu North-East, Ijebu North/Ijebu-Ode, and Ikenne/Sagamu/Remo North.[3] Each encompasses multiple local government areas, such as Abeokuta North/Odeda covering Abeokuta North and Odeda LGAs, reflecting demographic and geographic factors to balance population sizes across Nigeria's 360 House seats. Elections for these seats occur every four years during Nigeria's general elections, coordinated by INEC under the Electoral Act 2022, which mandates a first-past-the-post system where the candidate receiving the plurality of valid votes in a constituency wins.[13] On polling day, accredited voters cast ballots simultaneously for senatorial and House candidates using Bimodal Voter Accreditation System (BVAS) for biometric verification, with voting hours from 8:30 a.m. to 2:30 p.m., extendable for queued voters; results are manually collated from polling units to wards, local governments, and state levels before declaration.[13] Candidates must be nominated by registered political parties, meet age (35 for Senate, 30 for House) and citizenship requirements per the 1999 Constitution, and campaigns adhere to INEC timelines prohibiting vote-buying or incitement.[14]Pre-Fourth Republic Delegations
Second Republic (1979–1983)
The Nigerian National Assembly delegation from Ogun State during the Second Republic consisted of five senators, elected statewide across senatorial districts, and several House of Representatives members from federal constituencies apportioned by population under the 1979 Constitution. The Unity Party of Nigeria (UPN), a progressive party with strong roots in southwestern Yoruba areas, dominated the outcomes in Ogun, mirroring its statewide gubernatorial win and contributing to its national tally of 28 Senate seats and 111 House seats overall.[15] Prominent among the senators was Abraham Aderibigbe Adesanya, a lawyer and activist representing the Ijebu North East district, who aligned with UPN's emphasis on welfarism and federalism.[16] Another key figure was Jonathan Akinremi Odebiyi, representing areas in Yewa North (Ogun West), who rose to Senate Minority Leader, advocating for infrastructure like electricity and roads in rural constituencies while upholding UPN's platform.[17][18] The remaining senators, also predominantly UPN, focused on legislative oversight amid national debates on revenue allocation and economic policy, though specific names beyond these are sparsely documented in available records. House representatives from Ogun constituencies, such as those centered in Abeokuta, Ijebu-Ode, and Ilaro, similarly reflected UPN strength, participating in the lower chamber's 449 total seats to address local issues like agriculture and education funding. The full delegation's term, from inauguration in late 1979 until abrupt termination, exemplified the ethnic-regional dynamics of the era, with southwestern states like Ogun prioritizing UPN's free education and welfare programs against the ruling National Party of Nigeria's broader national appeals.[15] The assembly's dissolution occurred via military intervention on 31 December 1983, ending civilian rule and suspending all legislative activities.[15]Third Republic (1992–1993)
The Nigerian Third Republic's transition process culminated in legislative elections on 4 July 1992 for both the Senate and House of Representatives, as part of General Ibrahim Babangida's phased handover to civilian rule.[19] Ogun State's delegation reflected the national dominance of the Social Democratic Party (SDP), which secured all three senatorial seats amid competition from the National Republican Convention (NRC).[20] The elected senators were inaugurated alongside the National Assembly on 5 December 1992, but the body operated under constraints, with sessions limited before military intervention.[21] Ogun Central was represented by Monsurudeen Babatunde Osholake of the SDP, a figure later involved in state politics.[22] Ogun West elected Ayodeji Solomon Otegbola of the SDP, who served until the assembly's dissolution and was noted for his community leadership in Awori land.[23] Ogun East's seat went to Jubril Martins-Kuye of the SDP, a businessman-turned-politician who advocated for regional development during the brief term.[23] All senators aligned with the SDP's platform, emphasizing social democracy and economic restructuring, though substantive legislative output was minimal due to the republic's instability.[24]| Senatorial District | Senator | Party |
|---|---|---|
| Ogun Central | Monsurudeen Osholake | SDP [22] |
| Ogun East | Jubril Martins-Kuye | SDP [23] |
| Ogun West | Ayodeji Otegbola | SDP [25] |
Fourth Republic Delegations
10th National Assembly (2023–present)
The 10th National Assembly was inaugurated on 13 June 2023 following the general elections held on 25 February 2023.[26] The delegation from Ogun State comprises three senators and nine House of Representatives members, all elected on the platform of the All Progressives Congress (APC), which secured victory in every senatorial district and federal constituency in the state.[27] This uniform party representation underscores the APC's strong performance in Ogun, a southwestern state historically aligned with progressive politics. The Senate delegation includes Shuaib Salisu Afolabi representing Ogun Central Senatorial District, Justus Olugbenga Daniel representing Ogun East Senatorial District, and Solomon Olamilekan Adeola representing Ogun West Senatorial District.[4][5][28] Adeola, a returning senator who previously represented Lagos West, contested and won the Ogun West seat after relocating his political base to his home state.[29] In the House of Representatives, the nine members represent Ogun's federal constituencies: Abeokuta North/Obafemi-Owode/Odeda, Abeokuta South, Ado-Odo/Ota, Egbado North/Imeko-Afon, Egbado South/Ipokia, Ifo/Ewekoro, Ijebu North/Ijebu East/Ogun Waterside, Ijebu-Ode/Odogbolu/Ijebu North-East, and Ikenne/Shagamu/Remo North. All were initially elected as APC candidates in 2023.[27][3] A vacancy arose in Ikenne/Shagamu/Remo North following the death of the incumbent, Adewunmi Onanuga, on 15 January 2025; the resulting by-election on 17 August 2025 was won by APC candidate Adesola Ayoola Elegbeji, who was inaugurated on 9 October 2025.[30][31][32]| Constituency | Party |

9th National Assembly (2019–2023)
The Senate delegation from Ogun State consisted of three members, all affiliated with the All Progressives Congress (APC). Ibikunle Amosun represented Ogun Central, having secured victory in the February 2019 senatorial election with approximately 48.51% of the vote.[33][34] Ramoni Lekan Mustapha represented Ogun East, defeating PDP candidate Buruji Kashamu in a closely contested race where APC garnered 44.22% of the votes.[33][35] Tolulope Odebiyi represented Ogun West, winning with 29.36% of the vote against PDP's 22.6%.[33][36] This uniform APC representation aligned with the party's statewide dominance following Governor Dapo Abiodun's 2019 gubernatorial win, though Ogun East's margin highlighted competitive PDP support in eastern districts.[33]| Senatorial District | Senator | Party |

8th National Assembly (2015–2019)
The Ogun State delegation to the 8th National Assembly, serving from June 9, 2015, to June 9, 2019, comprised three senators and nine House of Representatives members, reflecting the state's three senatorial districts and nine federal constituencies. Elected during the April 2015 general elections under the All Progressives Congress (APC)-led national wave following the party's presidential victory, the delegation showed APC dominance with two senators and seven House members, while the Peoples Democratic Party (PDP) secured one senate seat and two House seats, primarily in eastern districts.[40][41][42] Senators The senate representatives focused on legislative priorities including budget oversight and constituency development, amid national debates on economic recession and anti-corruption measures.| Senatorial District | Name | Party |

7th National Assembly (2011–2015)
The delegation from Ogun State to the 7th National Assembly, serving from June 5, 2011, to June 4, 2015, comprised three senators and nine members of the House of Representatives, elected during the April 2011 general elections amid widespread support for the Action Congress of Nigeria (ACN) in the state.[44][45] The ACN, aligned with the gubernatorial victory of Ibikunle Amosun, captured all Senate seats and eight House seats, with the remaining House seat won by the People's Party of Nigeria (PPN).[45] This composition reflected Ogun's shift toward opposition parties against the incumbent People's Democratic Party (PDP) at the federal level, following competitive primaries and legal challenges resolved in favor of ACN candidates.[46] Senate Ogun Central was represented by Olugbenga Onaolapo Obadara of the ACN.[44] Ogun East was represented by Sefiu Adegbenga Kaka of the ACN, who secured 76,543 votes in the election and whose victory was upheld by the Supreme Court in December 2014 after PDP challenges.[44][46] Ogun West was represented by Akin Babalola Kamar Odunsi of the ACN.[44] All senators served their full terms without reported vacancies or by-elections.

6th National Assembly (2007–2011)
The Nigerian National Assembly delegation from Ogun State in the 6th Assembly (2007–2011) consisted exclusively of members from the People's Democratic Party (PDP), which secured all three Senate seats and nine House seats in the April 21, 2007, elections amid the party's national dominance and control of the Ogun State governorship under Gbenga Daniel. The elections faced widespread allegations of irregularities, including voter intimidation and ballot stuffing, as documented by international observers, though the Independent National Electoral Commission (INEC) certified the PDP victories. The Assembly was inaugurated on June 5, 2007, with Ogun's delegation reflecting PDP's organizational strength and incumbency advantage in the Southwest region. Senate Ogun's senatorial representation aligned with PDP's sweep:| Senatorial District | Senator | Party |
|---|---|---|
| Ogun Central | Iyabo Obasanjo-Bello | PDP |
| Ogun East | Ramoni Olalekan Mustapha | PDP |
| Ogun West | Felix Kolawole Bajomo | PDP |
5th National Assembly (2003–2007)
The delegation from Ogun State to the 5th National Assembly comprised three senators and nine House of Representatives members, reflecting the dominance of the Peoples Democratic Party (PDP) in the state's 2003 elections, where the party secured the governorship under Gbenga Daniel and all senatorial seats.[54][55][56] The National Assembly elections occurred on April 12, 2003, with the PDP benefiting from incumbent President Olusegun Obasanjo's popularity and organizational strength amid reported irregularities in some contests nationwide.[57] All three senators were PDP affiliates, marking a shift from the mixed representation in the prior assembly where opposition parties held seats. Ibikunle Amosun served Ogun Central, Olatokunbo Ogunbanjo represented Ogun East, and Iyabo Anisulowo held Ogun West.[34][55][58][54]| Senatorial District | Senator | Party |
|---|---|---|
| Ogun Central | Ibikunle Amosun | PDP [34] |
| Ogun East | Olatokunbo Ogunbanjo | PDP [55] |
| Ogun West | Iyabo Anisulowo | PDP [56] |
4th National Assembly (1999–2003)
The Ogun State delegation to the 4th National Assembly (1999–2003) comprised three senators and nine House of Representatives members, reflecting the Alliance for Democracy's (AD) regional dominance in the southwestern states following the 1999 elections that inaugurated Nigeria's Fourth Republic. The AD, a progressive party formed in 1998, secured all three senatorial seats in Ogun amid a broader sweep of legislative positions in Yoruba heartland states, contrasting with the People's Democratic Party's (PDP) national presidential victory.[60][61][62] The senators represented Ogun's three districts as follows:| Senatorial District | Senator | Party | Notes |
|---|---|---|---|
| Ogun Central | Femi Okurounmu | AD | Suspended in 1999 for alleging a senatorial plot to impeach President Olusegun Obasanjo; served full term despite the sanction.[62][63] |
| Ogun East | Olabiyi Durojaiye | AD | Former NADECO activist; focused on legislative oversight during term.[61][64] |
| Ogun West | Afolabi Olabimtan | AD | Academic and author; served one term until 2003.[60][65] |
Trends and Analysis
Party Representation Shifts
In the Fourth Republic, party representation in Ogun State's National Assembly delegation has largely reflected the Southwest's preference for opposition-aligned parties, with a temporary deviation during the 5th National Assembly (2003–2007). This period saw the People's Democratic Party (PDP) secure all three senatorial seats, coinciding with PDP's capture of the Ogun governorship under Gbenga Daniel, amid President Olusegun Obasanjo's regional push as a native of Abeokuta in Ogun Central.[69] The shift was driven by PDP's national incumbency advantages and local mobilization, overriding prior Alliance for Democracy (AD) dominance from the 4th Assembly (1999–2003), where AD held the senatorial positions as part of its Southwest sweep. From the 6th National Assembly (2007–2011) onward, representation pivoted back to opposition parties, initially under the Action Congress (AC), which evolved into the Action Congress of Nigeria (ACN) and later merged into the All Progressives Congress (APC) in 2013. This realignment consolidated ACN/APC control over the three senatorial seats across the 6th through 10th assemblies, underscoring causal factors like enduring regional loyalty to figures such as Bola Tinubu and dissatisfaction with PDP governance. In the House of Representatives, patterns mirrored this, with APC securing the majority of the nine seats in recent terms, though isolated opposition wins (e.g., PDP or Labour Party in select constituencies during the 10th Assembly) occurred due to local rivalries or vote splits.[6]| National Assembly Term | Senatorial Party Breakdown (Ogun East, Central, West) | Key Shift Driver |
|---|---|---|
| 4th (1999–2003) | AD, AD, AD | Regional opposition consolidation post-military rule |
| 5th (2003–2007) | PDP, PDP, PDP | PDP incumbency and Obasanjo's home-state influence |
| 6th–10th (2007–present) | ACN/APC dominant; all APC since 2015 | Reversion to Southwest opposition bloc via ACN/APC mergers and anti-PDP sentiment |
