Ronnie Flanagan

In July 2010, Flanagan appeared before the Iraq Inquiry into the UK's role in the Iraq War. In 2005, he had conducted a review into the UK's contribution to policing reform in Iraq. As he gave evidence, Flanagan had to apologise for the amount of acronyms in his report on Iraq, which was presented to the government in January 2006:

On 22 January 2007 a report by the Police Ombudsman for Northern Ireland, Nuala O'Loan, made findings of collusion between members of the proscribed paramilitary organisation, the Ulster Volunteer Force, and officers under the command of Flanagan. The reports were acknowledged by the then Chief Constable Sir Hugh Orde who apologised for the wrongdoing of his officers, and by the then British Secretary of State for Northern Ireland Peter Hain.

Since then he has served in Her Majesty's Inspectorate of Constabulary and was appointed as HM Chief Inspector of Constabulary in 2005. He was tasked to review the police arrangements in Iraq in December 2005 as part of the British involvement there. Following his retirement in December 2008, Denis O'Connor succeeded him as Her Majesty's Acting Chief Inspector of Constabulary.

The Police Ombudsman had criticised Flanagan's role in the RUC inquiry into the Omagh Bombing of 1998, in a report published in 2001, to which his response was that he would "publicly commit suicide" if he believed her report was correct, though he later apologised for the form of words he used.

In 1992 he returned to duty with the RUC as Assistant Chief Constable of Operations, later taking on the responsibilities of Operational Commander for Belfast. He was appointed as head of Special Branch in 1994 and was promoted to Acting Deputy Chief Constable the year after. He became the Deputy Chief Constable proper in 1996, and when Chief Constable Hugh Annesley retired later that year, Flanagan succeeded him. When the PSNI was established in 2001, he served as Chief Constable until his retirement the following year. He was replaced by Hugh Orde.

In 1990 he took on the role of Chief Superintendent and transferred to the Police Staff College in Bramshil where he was the First Director of the Intermediate Command Course, progressing to the Senior Command Course.

Born in Belfast, Flanagan joined the Royal Ulster Constabulary (RUC) in 1970 while studying physics at The Queen's University of Belfast. He served his first three years in the Queen Street Barracks before achieving the rank of sergeant and transferring to the Castlereagh station. He was promoted to Inspector in 1976. In 1982 he became a Detective Inspector in the Special Branch and was promoted the following year to Chief Inspector.
