In December 2009, Robinson announced that she would leave politics and withdraw from public life following prolonged periods of mental illness. In January 2010, it emerged that Robinson had an extramarital affair with a 19-year-old in 2008, and she and her husband were faced with allegations of financial impropriety related to the affair.
