Prince Charles has led tributes to police officers killed in the line or duty at a service in London, stressing the importance of the force's role amid today's security challenges.
About 2,000 people gathered in St Paul's Cathedral on Sunday for the service, including relatives and colleagues of those serving across the country and dignitaries including Home Secretary Amber Rudd.
Family members who lost loved ones offered prayers and lit candles in their honour, and the names of those who have died in the past year were read aloud to the congregation.
Charles paid tribute to those he said had "paid the ultimate sacrifice while safeguarding our families, our communities and our liberty".
In the order of service the Prince, who is patron of National Police Memorial Day, wrote: "For many of us, the security challenges of today further underscore the importance of the police and their ongoing commitment to protecting us all, despite the inevitable risks that they face on a daily basis."
Among those to be specially remembered was Pc Dave Phillips who was knocked down and killed by a teenage car thief in October last year.
His eight-year-old daughter Abigail lit a candle to remember the her father who died after he set down a tyre-puncturing stinger device in a bid to stop a stolen vehicle during a police pursuit in Wallasey, Merseyside.
Relatives of other officers killed in the line of duty represented Wales, Scotland and Northern Ireland as they too lit candles, while prayers were offered by family members.
