Obituary film of the lifelong Labour politician, Tony Benn, who was an MP for over 50 years. Born the son of a viscount, Benn was elected Labour MP for Bristol South East at the age of 25, and in his political career became a champion of the working class. After his father's death, Benn inherited the title of viscount, but he turned it down and with it a seat in the House of Lords, campaigning to change the Peerage Act, so that he could continue as an MP. Benn went onto serve as postmaster general and held cabinet posts as minister of industry and minister of energy under Harold Wilson. In 1981, he narrowly lost an election for Labour's deputy leadership to Dennis Healey. In 2001, Benn stepped down from the Commons in order to 'spend more time with politics'. He was president of Stop the War, campaigned against coalition cuts and ultimately became, in many people's eyes, a national treasure.
