The head of Bedfordshire Police, Jon Boutcher, is to stand down as Chief Constable.
He's been in the job for four years and has been a police officer for 35 years.
He says a lack of funding has been the biggest challenge which is being felt by all communities.
Mr Boutcher will continue leading Operation Kenova, an historic investigation into a number of alleged murders, kidnaps and tortures in Northern Ireland.
His last working day with the force will be on 5 July, and Police & Crime Commissioner Kathryn Holloway will be responsible for appointing his successor.
