With Britain's first-ever political leaders' television debate imminent, award-winning reporter Michael Cockerell uncovers what it's like to take part in these contests and how leaders try to win them. He tells the inside story of why it has taken so long for such debates to arrive in the UK. The programme features candid interviews with US Presidents and their advisers on the tricks of the debate trade. Blending new film and behind-the-scenes footage, some never seen before, it's a tragicomic tale of high politics and low cunning. From John F Kennedy and Richard Nixon through to Barack Obama, candidates are seen being prepared for their debates, then in the sometimes funny, sometimes disastrous results on live television. Cockerell shows why for our would-be next Prime Ministers - Gordon Brown, David Cameron and Nick Clegg - the three debate stages across Britain will be what one former US President calls 'Tension City'.

Frustrated at a new moderate Conservative government and deprived of a promotion to a senior position, chief whip Francis Urquhart prepares a meticulous plot to bring down the Prime Minister then to take his place.

This topical debate series based on Any Questions? typically features politicians from at least the three major political parties as well as other public figures who answer pre-selected questions put to them by a carefully selected audience.
