Question Time, the BBC's premier political programme chaired by David Dimbleby, was in Oxford on 26 April.
He was joined by the Minister for Public Health, Caroline Flint MP, the former Conservative cabinet minister Douglas Hurd, the Liberal Democrat work and pensions spokesman David Laws MP, Plaid Cymru's Director of Elections, Adam Price MP and the journalist and writer Douglas Murray.
CAROLINE FLINT MP
Career: Caroline Flint is the Minister for Public Health. Having been elected as the Labour MP for Don Valley in 1997, she served as a Private Secretary to Peter Hain in both the Department of Trade and Industry and the Foreign Office.
In 2002, she moved to work under John Reid as Leader of the House of Commons, before joining the Home Office in June 2003.
She has been a minister in the Department of Health since May 2005, with a responsibility for managing public health campaigns such as the banning of smoking in bars and restaurants, which will come into effect on July 1st.
In February, she announced that she will be Hazel Blears' campaign manager for the deputy leadership of the Labour Party.
Career: Douglas Hurd is a senior Conservative politician who has held a number of key posts in government, including foreign secretary and home secretary.
In 1990, after serving in the government of Margaret Thatcher, he ran for the leadership of the party.
He came third behind Michael Heseltine and John Major, who kept him in the cabinet as Foreign Secretary. During the following years, Hurd oversaw Britain's response to the collapse of the Soviet Union, as well as the first Gulf War and the unrest in the Balkans.
From 1983 until his retirement in 1997, he was MP for Witney, succeeded by the current Conservative leader David Cameron. On his retirement, he was made a Baron, and continues to be active in politics in the House of Lords.
DAVID LAWS MP
Career: David Laws is the Liberal Democrat's work and pensions spokesman. After a successful career in investment banking, during which he was a vice president of JP Morgan, he entered politics in 1994, working first as an economic advisor to the Lib Dems and later as their director of policy and research.
Following his election to parliament in 2001 as the MP for Yeovil, Laws became the party's work and pensions spokesman in 2005.
In recent weeks he has been an outspoken critic of government compensation for people who have lost out in the pensions crisis, saying: "Those who have lost their pensions will not forgive MPs who do not back a fair compensation package".
Regarded as being on the right-wing of the Liberal Democrats, last month it was reported that he had been offered a chance to defect to the Conservative shadow cabinet by Tory shadow chancellor George Osborne - an opportunity which he declined.
ADAM PRICE MP
Career: Adam Price is the Plaid Cymru MP for Carmarthen East, and the party's Director of Elections. He is a Welsh nationalist who supports the long-term aim of full national status for Wales.
His outspoken criticism of Tony Blair and the Iraq war has made headlines and led to his ejection from the House of Commons chamber in March 2005 for refusing to withdraw his accusation that Tony Blair had "misled" parliament over the invasion.
In October 2006 he opened a three-hour debate on an inquiry into the Iraq war, supported by the Scottish National Party and Plaid Cymru, as well as a small number of rebel Labour MPs.
In 2002 he won the Spectator Magazine Parliamentary Inquisitor of the Year for his expose of a letter from the prime minister to his Romanian counterpart on behalf of the Labour donor Lakshmi Mittal.
Career: Douglas Murray is a journalist and writer, who was recently described in the New York Sun as "Britain's only neo-conservative".
His book, Neo-conservatism: Why We Need It, was hailed as "the Right's answer to Michael Moore", and his comments about the rise of extremist Islam in Holland have led to his needing police protection when visiting the country.
In October, he wrote in The Guardian on the Iraq war: "For a conservative realist, the presence of all those jihadists in one place, with thousands of our troops there too, presents an opportunity to cut the number of terrorists a bit.
"For a conservative idealist, the chance to pull apart the jihad in Iraq not only improves our own security situation (unless zero attacks on the American homeland since 9/11 is some kind of miracle), it also helps Iraq recover from decades of brutality."
