In the 2006 Liberal Democrats leadership election, Sir Menzies Campbell was elected to succeed Charles Kennedy as Leader of the Liberal Democrats, the third-largest political party in the United Kingdom. On 5 January 2006, following a period of heavy speculation about both his leadership and his personal life, party leader Charles Kennedy called for a leadership contest to allow party members to decide if his leadership should continue. On 7 January 2006, following public pressure from many prominent Liberal Democrats to stand down, including twenty-five Members of Parliament who publicly announced they would refuse to serve on the party's frontbench if he did not stand aside, Kennedy announced that he would not be standing in the leadership election, resigning as party leader with immediate effect.

The downfall of Charles Kennedy In the wake of the 2005 general election, Kennedy's leadership came under increased criticism from those who felt that the Liberal Democrats could have done even better at a time when, arguably, the Official Opposition, the Conservative Party, were in a relatively weak position and the Labour Government remained unpopular in the aftermath of the invasion of Iraq in 2003. Leadership speculation was renewed in later 2005. Following the election of David Cameron as Leader of the Conservative Party in December 2005, it was widely reported that senior members of the Liberal Democrats had told Kennedy that he must either "raise his game" or resign. A number of issues led to the pressure on Kennedy. There was concern behind the scenes about his problems with alcohol, how he
