The United Kingdom general election debates of 2010 consisted of a series of three leaders' debates between the leaders of the three main parties contesting the 2010 United Kingdom general election: Gordon Brown, Prime Minister and leader of the Labour Party; David Cameron, Leader of the Opposition and Conservative Party; and Nick Clegg, leader of the third largest political party in the UK, the Liberal Democrats. They were the first such debates to be broadcast live in the run-up to a UK election.
The debates ran without a break for 90 minutes and were broadcast weekly by ITV, BSkyB and the BBC over three successive Thursday evenings starting on 15 April. They were moderated by Alastair Stewart, Adam Boulton and David Dimbleby respectively. The first half of each debate focused on a particular theme (domestic, international and economic affairs), before general issues were discussed. The questions were not disclosed to the leaders before the debate.
In addition to the leaders' debates, on 29 March, the three main parties' financial spokesmen participated in a debate focusing on the economy, with the Chancellor of the Exchequer Alistair Darling debating with the Shadow Chancellor George Osborne and Liberal Democrats' Treasury spokesman Vince Cable on Channel 4. Debates also took place between 19 April and 5 May, a series of debates also took place on the BBC political TV series The Daily Politics, between members of the incumbent Labour Cabinet and their Conservative, Liberal Democrat counterparts and representatives from the Green Party, the Scottish National Party, Plaid Cymru and the UK Independence Party.
