Cambridgeshire’s Chief Constable will be retiring from the force this summer.
Simon Parr will be retiring at the end of July after a 32-year career.
Mr Parr has been with the Cambridgeshire force for five years and previously served with Hertfordshire and Sussex police.
He said: “It is with mixed feelings that I am formally announcing my retirement from policing after nearly 32 years’ service.
“There is never a perfect time to leave a role that I have enjoyed as much as this.
“But, with a new government in place, a new round of spending challenges to be met – and, no doubt, other unseen challenges to be tackled – this seems in my judgement to be the right time for me to hand over the stewardship of the organisation to someone who will lead the constabulary through the next five years,” he added.
“It has been an enormous privilege to spend so much time in public service.
“I am honoured to have held the office of constable for so long.”
Deputy Chief Constable Alec Wood will become Acting Chief Constable until a recruitment process takes place.
Police and Crime Commissioner, Sir Graham Bright, has paid tribute to Mr Parr.
He said: “Simon leaves behind a strong, effectively run constabulary that is well placed to face the challenges ahead.
“While I am sorry to see him go I would like to thank him for all he has done and wish him well for the future.”
