Once touted as a frontrunner to become Britain's most senior police officer, Sir Norman Bettison's career has been dogged by the Hillsborough disaster.
He resigned in the wake of last month's Hillsborough Independent Panel's report, which renewed allegations he was involved in the police's "black propaganda" campaign over the disaster.
- A member of South Yorkshire Police's internal review group on Hillsborough, in 1993 he became Assistant Chief Constable of West Yorkshire Police
- Made Chief Constable of Merseyside Police in 1998, prompting anger from families of Hillsborough victims and resignations in Merseyside Police Authority
- Named an honorary fellow of Liverpool's John Moores University and retired in 2004
- Knighted for services to policing in 2006, before returning to become West Yorkshire Police's chief constable in January 2007
- Tipped by media in 2008 to succeed ousted Metropolitan Police Commissioner Sir Ian Blair, but ruled himself out of race
- Denies wrongdoing over Hillsborough disaster, but retired after being faced with an Independent Police Complaints Commission investigation
