What were the implications of the 1963 Peerages Act?
Fifty years ago this summer - 31 July 1963 to be precise - Labour politician Tony Benn finally won the right to renounce his hereditary peerage and return to the Commons.
Mr Benn inherited the title of Viscount Stansgate when his father died, barring him from the Commons where he had been serving his Bristol South East constituents for 10 years.
The MP regained his seat in the Commons after winning a by-election held weeks after the Peerages Act came into force.
But the Act would also have significant implications for the Conservatives, as Susan Hulme explores.
