Second World War codebreaker Alan Turing, has been given a posthumous royal pardon for a 61-year-old conviction for homosexual activity - still an offence in the UK in the 1950s.

The Cambridge mathematician has been hailed a national hero for his work to help break the German Enigma Code at Bletchley, near Milton Keynes during the war.
