BBC Trust chairman Chris Patten quits after heart surgery

Chris Patten, whose tenure as head of the BBC's governing body was dominated by the fallout from a string of paedophilia scandals at the broadcaster, resigned today after undergoing major heart surgery.
Patten, a former Conservative politician and the last British governor of Hong Kong before the handover to China in 1997, said he had been admitted to hospital in late April after suffering serious chest pains.
The BBC, the world's largest public broadcaster, said that the 69-year-old Patten would be "standing down with immediate effect on health grounds following major heart surgery".
He took the post as chairman of the BBC Trust in April 2012.

Patten, who is also chancellor of the prestigious Oxford University, said he underwent a combination of bypass surgery and angioplasty and had suffered no permanent damage to his heart.
