Chief Constable Campbell said: “It has been an immense honour to have served the public and to have led the Force for the past four years.

"Throughout my career I have seen policing change significantly with complexity and volume of crime, new technology that has transformed policing, and ever changing demand on the police as a service.

“The one thing that has remained throughout is the officers, staff and volunteers, who work so hard and on a daily basis put their lives on the line to serve and protect the public."

Chief Constable Campbell was made Deputy Chief Constable of Thames Valley Police in May 2015 and he was later appointed Chief Constable in April 2019.

In 2015, Chief Constable Campbell's service was recognised by the Queen as he was awarded the Queen's Police Medal for his significant contributions to policing.

Thames Valley Police and Crime Commissioner Matthew Barber said: 

“On a personal level it has been a privilege to work with John over recent years, but more widely the Thames Valley has been fortunate to have such a dedicated public servant as Chief Constable.

“Within the force he is universally well regarded, mixing great care for each and every officer, staff member and volunteer, with a determination to succeed.

“To the public and partners John Campbell has been unstinting in his support to deliver excellent policing, often in very difficult circumstances, to every community across Thames Valley.”
