A former police officer from Sheffield is set to retire from his post as head of Scotland Yard.
Sir Bernard Hogan-Howe will remain in his post as Commissioner of the Metropolitan Police until February 2017 to allow the Home Secretary and Mayor of London to appoint a successor.
The 58-year-old, who was appointed in September 2011, said: "It has been a great privilege to be the Met's Commissioner. I have loved my time in the role and I have loved being a police officer.
"It's the most rewarding of jobs to protect good people and lock up the bad guys."
Home Secretary Amber Rudd said: "I want to thank Sir Bernard Hogan-Howe for the leadership he has shown as Commissioner, and his work to keep the communities of London safe and the United Kingdom secure against the backdrop of a heightened terror threat.
"Sir Bernard has had a long and distinguished career as a determined crimefighter and an inspirational senior officer. He has shown remarkable and consistent dedication to public service."
Mr Hogan-Howe was brought up in Ecclesfield, attended Hinde House School in Wincobank and joined South Yorkshire Police in 1979.
He worked his way up the ranks in the force and became a Superintendent in August 1993 before moving to Merseyside Police in August 1997 as Chief Constable.
