From the moment Margaret Thatcher met the Saatchi brothers, elections campaigns would never be the same again.

Suddenly, every aspiring PM wanted a fast-talking, sharp-thinking ad man on their team to help dazzle voters. But what were the consequences of their fixation with the snappy and simplistic?

Sam Delaney embarks on a journey to expose the shocking truth behind the general election campaigns of the last four decades. Everything is here - from the man who snorted coke in Number 10 to the politician who fell in love with her own ad exec, from the fist-fights in Downing Street to the all-day champagne binges in Whitehall offices.

Sam Delaney talks to the men at the heart of the battles - Alistair Campbell, Peter Mandelson, Tim Bell, Maurice Saatchi, Norman Tebbit, Neil Kinnock - and many more.

Dark, revealing and frequently hilarious, Mad Men and Bad Men tells the story of how unelected, unaccountable men ended up informing policy - and how the British public paid the price.
