As the Hillsborough Inquiry continues with the role of police and police cover-ups at the forefront of the investigation, Sir Norman Bettison has tended his immediate resignation as the West Yorkshire Police Chief Constable, following calls for him to resign, after it came to light that Bettison boasted about his Hillsborough cover-up attempt to Shadow Transport Secretary, Maria Eagle, saying that he tried to concoct a story that all the Liverpool fans were drunk.

Bettison, who attended the match as a spectator, defended his role in the aftermath of the disaster following revelations that 116 witness statements were modified by police in an attempt to smear fans, who attended the game that day. He said: "I never altered a statement nor asked for one to be altered."

Mark Burns-Williamson, who resigned from his role as chairman of West Yorkshire Police Authority, so he could stand in November's police and crime commissioner election, earlier added his voice for Bettison to stand down, saying it was in the 'best interests' of the force for him to stand down from his role now rather than wait for his March retirement date.

A police authority special committee will continue to discuss Bettison's future and investigate these new claims.
