Simon Cowell has pledged his support for the Innocence Project, becoming an ambassador for the New York based charity which works to free innocent people from US prisons.

The music mogul was inspired to partner with the charity after seeing Archie Williams, who was wrongly incarcerated for 36 years, perform on America's Got Talent. Cowell commented 'Archie’s performance is probably the single most important one in the history of America’s Got Talent... While Archie’s voice is extraordinary, unfortunately his experience of being sent to prison for a crime he didn’t commit is much more common than most people realise... I’m honoured to become an ambassador for the Innocence Project and want to do what I can to help more people like Archie'.
