Introduction

Forty years ago this spring, Britain's governing party was caught up in a leadership election after Labour prime minister Harold Wilson's shock announcement that he was stepping down. Six cabinet ministers vied to replace Wilson, with foreign secretary Jim Callaghan emerging as victor after three rounds of voting, on 5 April 1976. To mark the anniversary, James Naughtie presents an evening of BBC archive programmes looking back at the political career of Jim Callaghan.
