Question Time, the BBC's premier political programme chaired by David Dimbleby, was in London on Thursday 15 February.
He was joined by Lord Hattersley, Lord Tebbit, Liberal Democrat Treasury spokesperson Julia Goldsworthy, columnist Richard Littlejohn and war correspondent Janine di Giovanni.
Career: Roy Hattersley is a senior Labour grandee who held a number of ministerial positions under the 1970s governments of Harold Wilson and James Callaghan.
From 1983-1987 he served as Deputy Leader and Shadow Chancellor under Neil Kinnock, helping modernise the party.
He has recently called for Tony Blair to resign, however, and endorsed Gordon Brown as the next prime minister, saying: "I think Gordon Brown increasingly becomes the ideal next leader of the Labour party... somebody with visibly and almost ostentatiously contemptuous of spin who wants simply to say it as it is."
On Muslims' place in society today, he has recently written: "Press has combined with police to make them feel that the whole Islamic community is under suspicion."
Career: Norman Tebbit was Trade and Industry Secretary, Chancellor of the Duchy of Lancaster and Conservative Party chairman under Margaret Thatcher's premiership.
Popular among grass-roots members, he forged a reputation for being tough on the unions and the unemployed.
Controversially, he invented the "Cricket test", in which he said the "Britishness" of people from ethnic minorities should be determined by whether or not they supported England at cricket.
After this week's revelations about David Cameron having used cannabis at Eton, he urged the Tory leader to reveal if there were any other "exposes" to come, saying: "My advice to him now would be 'Get it out of the way, get it over with and it will be a seven-day wonder. If you don't, people will keep turning up with another expose'."
Career: Julia Goldsworthy is the Liberal Democrat Treasury spokesperson.
Winning the seat of Falmouth and Cambourne in the 2005 election, she became the youngest MP in the House of Commons, and was appointed a party spokesperson on health in the same year.
She remains the youngest member of the Liberal Democrat shadow cabinet.
Last year, she competed in the Channel 4 series The Games, finishing as a runner-up.
Career: Richard Littlejohn is a controversial columnist for the Daily Mail and fierce opponent of "political correctness".
He has been a journalist since leaving school at the age of 16 and working for local Essex newspapers.
He was previously a columnist for the Sun and a broadcaster for Sky News.
On the recent letter-bomb campaign, he said: "Be honest, until you heard that a woman had been injured, how many of you suppressed a cheer at the news that someone had sent a letter bomb to the company which runs London's congestion charge?"
