Veterans have gathered at Bletchley Park near Milton Keynes to celebrate the 70th anniversary of a computer credited with stopping Hitler.

Alan Turing is expected to receive a full parliamentary pardon.
Second World Warcode-breaker Alan Turing has been given a posthumous royal pardon for a 61-year-old conviction for homosexual activity.
Dr Turing, who was pivotal in breaking the Enigma code, arguably shortening the Second World War by at least two years, was chemically castrated following his conviction in 1952.
His conviction for "gross indecency" led to the removal of his security clearance and meant he was no longer able to work for Government Communications Headquarters (GCHQ) where he had continued to work following service at Bletchley Park during the war.
Dr Turing, who died aged 41 in 1954 and is often described as the father of modern computing, has been granted a pardon under the Royal Prerogative of Mercy by the Queen following a request from Justice Secretary Chris Grayling.
"Dr Alan Turing was an exceptional man with a brilliant mind," Mr Grayling said.
Bletchley Park, the home of the second world war codebreakers, is to unveil the latest stage in its restoration project.

The new exhibition includes quotes from the women, telling the story of their time at Bletchley Park.
