Some of it was moderately revealing, but the money shot was the blond bombshell, live and unleashed.

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.

Michael Cockerell tells the story of how prime ministers have coped with life after Number Ten, after Tony Blair became the youngest member of the ex-PMs' club for a hundred years. The film reveals who left office bankrupt, who did TV commercials for Cheshire cheese, who had his own chat show and who has never had a single happy day since leaving Number Ten.

It begins with cheers but almost always ends in tears. Yet, as the election looms, competition for the top job grows ever more intense. Why? The hours are terrible, money so-so, job security non-existent. On the plus side, there's free accommodation in central London and probably more power over your country than any other leader in the western world. With the help of the present and previous incumbents, Michael Cockerell offers the first "how to" guide to the job of prime minister.
