THE body representing police officers in the Thames Valley claims Christmas has been “cancelled” after the force made shift changes at short notice.

Thames Valley Police has changed officer shifts on Christmas Eve from 2pm-10pm to 8pm-4am and officers will have to clock back on shift at 3pm.

The Police Federation claims the change contravenes regulations which require at least 90 days’ notice.

Thames Valley Police said it would look into the issue.

Assistant Chief Constable John Campbell said: “We must ensure we have the right number of officers on duty at the right times to provide the best service to the public.

“The welfare of officers is always a consideration when we have to make changes and we do all we can to minimise disruption as well as ensuring changes are in line with police regulations.”
