Tony Benn was one of the few British politicians who became more left-wing after having actually served in government.

He became the authentic voice of the radical left with the press coining the term Bennite to describe the policies espoused by those resisting attempts to move the Labour Party to the middle ground.

As such, he became a bogeyman for the right in British politics, with delegates to Conservative conferences displaying Ban the Benn badges in the style of CND’s Ban the Bomb logo.
