The family of PC Keith Palmer, who was murdered in the Westminster terror attack, have been joined at his funeral by thousands of police officers.
The 48-year-old father and husband was stabbed to death by Khalid Masood as he carried out his duties on the cobbled forecourt of the Palace of Westminster.
PC Palmer's funeral cortege, including his hearse topped with a floral tribute reading No 1 Daddy, left the palace, where his coffin laid in rest overnight, through the Carriage Gates he died defending.
PC Palmer's coffin travelled slowly and amid silence along the capital's usually bustling streets, avoiding the scene of last month's atrocity on Westminster Bridge on its journey to Southwark Cathedral, in central London.
Around 50 members of PC Palmer's family including his wife, child, mother and father, brother and sisters attended the cathedral service, led by the Dean of Southwark The Very Reverend Andrew Nunn to be followed by a private cremation.
The Met said more than 5000 officers from the force and across the country were expected to gather in central London for the service and to line the route, which has seen dozens of roads closed to traffic for hours.
Thousands more officers and staff marked two-minutes' silence at 2pm.
Columns of officers in dress uniform, many with service medals pinned to their jackets and wearing white gloves, lined up near the cathedral as on-duty colleagues involved in the large security operation stood guard.
The procession was led by the Metropolitan Police Colour Party and a Black Escort of mounted officers before the coffin was carried into the cathedral by colleagues and friends of PC Palmer.
Two National Police Air Service helicopters also performed a flypast and aerial salute.
