The “inspiring leader” of Devon and Cornwall Police is to leave after five years as chief constable.

Stephen Otter, who is in the last year of a fixed term contract, has been successful in his application for the role of Her Majesty’s Inspector of Constabulary.

This independently assesses police forces and policing activity, ranging from neighbourhood teams through serious Crime to the fight against terrorism.

Mr Otter, who joined the force in 2007, said: “I am extremely happy with the policing achievements in Devon and Cornwall during the past five years and I have been really encouraged by the dedication and commitment I have seen from officers and staff. The results and improvements are a direct result of their hard work and determination to deliver the best possible service to the local communities.

“Whilst I look forward to my new challenge I will also miss leading policing in Devon and Cornwall. I have been inspired and energised by people I have worked with every day over the past five years.”

Mr Otter’s contract could not be extended past January next year because of the introduction of a Police & Crime Commissioner this November. His leaving date has yet to be agreed.

Mike Bull, chairman of Devon and Cornwall Police Authority, congratulated Mr Otter on his appointment but added that “naturally” his feelings were “mixed.”

“Whilst I am delighted for him and his future I am sorry for Devon and Cornwall Constabulary, as he has been an inspiring leader.

“He has led the force through exceptional challenge and change, both financially and culturally over the past five years. He has taken the force from being an average performing force to one of the top in the country, and the latest performance figures speak for themselves,” said Mr Bull.

He said that the force was in the top ten nationally in nine out of 11 categories – and in eight of those categories, in the top five places.

For “respect and fairness” the force was ranked first out of 42 forces and second for people thinking the force did a “good or excellent job.”

Mr Bull added: “It has been a privilege to have worked in partnership with Steve over the past five years. He will be missed by the authority and the force but I also believe that he will be missed by many people across Devon, Cornwall and the Isles of Scilly.”
