Lefties is a three-part 2006 BBC documentary series investigating some aspects of the extreme Left of British politics in the 1970s. The series was commissioned by the then Controller of BBC Four, Janice Hadlow. Lefties was produced as a companion series to Tory! Tory! Tory! an overview of the New Right and Thatcherism. Hadlow believed that so called 'serious television' was vital in driving ideas, and her commissions were a critical and ratings success.
