Question Time, the BBC's premier political debate programme comes from Cardiff on Thursday 25 February.
The panel includes the senior Labour politician Peter Hain MP, the shadow defence secretary Dr Liam Fox MP, the Plaid Cymru leader Elfyn Llwyd MP, UKIP's Nigel Farage MEP and the journalist and broadcaster Janet Street Porter.
Peter Hain is a senior Labour politician, who has held a number of cabinet posts, including secretary of state for Wales, secretary of state for Northern Ireland and work and pensions secretary.
He was born in Kenya and grew up in South Africa, and was famous for his involvement in the anti-apartheid movement.
In 2008, he was forced to stand down from the cabinet after an investigation was launched into donations to his deputy leadership campaign. After what he described as a "a soul-searing experience", the investigation was dropped with no charges.
He was in Tony Blair's cabinet when the decision was taken to invade Iraq. The controversy surrounding the build up to war will be under scrutiny again next week when Gordon Brown gives evidence to the Chilcot inquiry.
DR LIAM FOX
Liam Fox has been Conservative shadow secretary of state for defence since 2005.
A doctor by profession, he entered politics as a student, when he was president of the Glasgow University Conservative and Unionist Association.
He first ran, unsuccessfully, for Parliament in 1987, and was elected as MP for Woodspring in 1992. A year later, he became parliamentary private secretary to the then home secretary, Michael Howard.
Following the Conservative defeat in 1997, he joined the opposition front bench, and has held a number of high-profile posts, including shadow health secretary, co-chairman of the party and shadow foreign secretary. He stood for the party leadership in 2005.
He recently called for Iran to be confronted over its nuclear ambitions, with all options remaining on the table.
He is appealing against Sir Thomas Legg's request for repayment of £24,000 in his parliamentary expenses.
Elfyn Llwyd is the leader of the Plaid Cymru group in Westminster and Member of Parliament for Meirionydd Nant Conwy.
Prior to his election in 1992, he worked as a barrister.
In 2004, he and other Plaid Cymru politicians famously launched a campaign to impeach then Prime Minister Tony Blair for his role in the Iraq war.
Earlier this month he said he had a memo showing Tony Blair and George Bush struck a secret deal to invade Iraq a year before the 2003 war and offered to send it to the Chilcot inquiry.
NIGEL FARAGE MEP
Nigel Farage is the former leader of the UK Independence Party.
Having joined the Conservative Party as a schoolboy, he left in 1992 in protest over John Major's signing of the Maastricht Treaty and went on to join UKIP in 1994.
In 1999, and again in 2004 and 2009, he was elected to the European Parliament and is currently leads UKIP's 13 MEPs. UKIP leads the multi-national Eurosceptic group EFD - Europe of Freedom and Democracy.
He hopes to unseat Commons Speaker John Bercow and win UKIP its first seat in Buckingham at the general election.
JANET STREET PORTER
Janet Street Porter is the editor at large of the Independent on Sunday, having been the paper's editor between 1999 and 2002.
She began her Fleet Street career at the age of 21, and has subsequently established herself as a journalist, a BAFTA award-winning TV producer and broadcaster.
Famous for her outspoken views, she describes herself as a "shame-free zone". She has appeared as a contestant in a number of reality TV shows, including So You Think You Can Teach and I'm A Celebrity, Get Me Out Of Here, and is vice president of the Ramblers Association.
Commenting this week on claims of bullying in Downing Street, she said: "Disraeli said 'a person's fate is their own temper'. We shall see if it's true for Mr Brown."
