World War II codebreaker Alan Turing has been pardoned by the queen over a criminal conviction for homosexual acts in the 1950s.
Turing's pardon followed a long-running parliamentary campaign backed by supporters, including Stephen Fry.
Issuing such a pardon using the Royal Perogative of Mercy is highly unusual.
Supporters of the campaign celebrated.
However, Turing was just one of thousands of men convicted under the law.
