Political Mavericks. John Sergeant’s documentary looks at those politicians who defy convention. Monday, BBC4, 9pm

From the BBC website:

“As three unconventional politicians - Ken Livingstone, Boris Johnson and Brian Paddick - battle it out to be Mayor of London, John Sergeant tells the story of Westminster’s lone riders, the rebels who have refused to play by the rules. Combining interviews and archive, he explores our enduring fascination with politicians who dare to be different and do their own thing.”
