Alan Turing will be the inspiration for one of the country’s biggest gay festivals.

The world war two codebreaker, who lived in Wilmslow, provides the theme for the Manchester Pride Parade.

The theme will be ‘Queer’d Science’ in honour of the 100th anniversary of Turing’s birth.

The festival celebrates the city’s gay, lesbian, bisexual and transgender community and raises money to fight HIV.

More than 3,000 people are expected to take part and in previous years the event has attracted high profile names including stars from Coronation Street and actor Sir Ian McKellen. Turing, a computer pioneer and mathematician, was prosecuted for gross indecency for having relations with a man in 1952.

The genius, whose work at Bletchley Park helped crack the Nazi Enigma cipher, committed suicide two years later.

In 2009, Gordon Brown issued a public apology for the government’s treatment of Turing. Last year, supporters launched an unsuccessful online petition demanding a pardon.

In Wilmslow fans are trying to instigate their own monument to the man.

There is a blue plaque to mark where Turing lived on Adlington Road until he committed suicide.

But supporters have said there should be a more lasting monument such as a statue or road name. At the last Wilmslow Town Council meeting it was suggested to name the new estate at the former Oaklands school site after Turing.

Coun Jim Crockett said:  “There is the plaque on Adlington Road but I’m keen to see something more to mark his good work.”

The parade will take place on August 25. Tickets for the festival will go on sale in May 2012.
