The Prince of Wales has led the congregation at an emotional service for fallen officers to mark National Police Memorial Day.
Charles attended the 10th annual service to honour all officers killed in the line of duty from England, Scotland, Northern Ireland and Wales since modern policing began in 1972.
After the service, Charles met 80 colleagues, friends and family of fallen officers at an informal reception.
"Our courageous policemen and women routinely endure hazardous environments in order to defend us and protect all our freedoms," the Princes of Wales said.
"They will never be forgotten and their proud legacy inspires us and will always live on."
