Question Time, the BBC's premier political programme chaired by David Dimbleby, was in London on 10 May.
In this week's programme the panel discussed Tony Blair's legacy after 10 years as prime minister.
David Dimbleby was joined by EU Trade Commissioner Peter Mandelson, leader of the Liberal Democrats Sir Menzies Campbell, Kenneth Clarke and columnist Jane Moore.
Career: Peter Mandelson is the British Commissioner to the EU on Trade. He is one of the Prime Minister's closest allies and is regarded as one of the key architects of New Labour.
After many years of involvement in the youth wing of the Labour Party, he became the party's director of communications in 1985, running Labour's 1987 election campaign.
In 1992 he entered parliament as the MP for Hartlepool, and coordinated the 1997 election campaign, which brought Tony Blair to power with a landslide victory.
He has held a number of high-profile posts in government, including Secretary of State for Trade and Industry and Secretary of State for Northern Ireland. He has been the European Commissioner for Trade since 1994.
SIR MENZIES CAMPBELL MP
Career: Sir Menzies Campbell is leader of the Liberal Democrats.
After a career as an Olympic athlete, he entered parliament in 1987. In March 1996 he became, party leader, succeeding Charles Kennedy.
He has been an outspoken critic of the war in Iraq and has led calls for an inquiry into the conflict.
His party recently performed poorly in the local elections after losing votes to a resurgent Tory party, leading the Lib Dem trade and industry spokesperson to suggest that Sir Menzies "might well" quit before the next general election. This has been denied by party insiders, who say he is "looking forward to the battle ahead."
KENNETH CLARKE MP
Career: Ken Clarke QC MP was Chancellor of the Exchequer from 1993 to 1997 and was Gordon Brown's immediate predecessor.
He is one of Britain's longest-serving MPs, having been first elected as Conservative MP for Rushcliffe in 1970.
He remains one of the party's most senior figures, despite three unsuccessful attempts at the leadership.
Early this year he was appointed by David Cameron to head the party's democracy task force which was considering ways of improving the workings of government.
Career: Jane Moore is an outspoken columnist for The Sun, and a regular contributor to television programmes including Have I Got News For You and Channel 4's Dispatches.
She recently wrote of suggestions for green taxes on carbon emissions: "The eco-bandwagon is splintering under the strain of so many corpulent, overpaid MPs desperate to clamber aboard for the latest round trip of gesture politics that leads nowhere but will still blight the lives of ordinary people."
