POLICE forces across the North-East staged silent tributes today as the body of murdered Pc Keith Palmer went on its final journey through the city he once protected.

Thousands of police officers lined the route of his funeral cortege in central London.

The 48-year-old was stabbed to death by Khalid Masood as he carried out his duties on the cobbled forecourt of the Palace of Westminster.

The Northern Echo:

SOMBRE: The coffin of Pc Keith Palmer leaves Westminster's Chapel of St Mary Undercroft in London and makes its way to Southwark Cathedral after resting overnight.

An Army veteran from Darlington, who was among the first on the scene of the Westminster attack, tried to save the life of PC Palmer.

Tony Davis, who served 22 years in the military, is now a GB Boxing performance coach and was leaving a press event with a group of boxers when he saw the attack taking place.

Mr Davis attended the funeral this afternoon to pay his respects, but said the day was not about him, but the "family, friends and colleagues" of PC Palmer.

PC Palmer's funeral cortege, led by the Metropolitan Police Colour Party and a "Black Guard" of mounted officers, left the palace, where his coffin laid in rest overnight, on its journey to Southwark Cathedral, in central London.

Pc Palmer's coffin travelled along 2.6 miles of the capital's usually bustling streets, avoiding the scene of last month's atrocity on Westminster Bridge, to arrive for the 2pm ceremony.

A floral tribute left on top of the hearse read: "No 1 daddy".

Around 50 members of Pc Palmer's family including his wife, child, mother and father, brother and sisters attended the cathedral service, which was led by the Dean of Southwark The Very Reverend Andrew Nunn and followed by a private cremation.

Met commissioner Cressida Dick, the first female head of Scotland Yard in its 188-year history, attended the funeral in her first public engagement in her new role.

The Met said more than 5,000 officers from the force and across the country gathered in central London for the service and to line the route, which has seen dozens of roads closed to traffic for hours.

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.

Members of the public began to line the barriers several hours before the service began.

Chief Constable Sara Thornton, head of the National Police Chiefs' Council, said the scale of the funeral was unprecedented as officers held a two-minutes silence at 2pm.

She told the BBC's Victoria Derbyshire Show: "I don't think we will have ever seen a police funeral of this size.

"Officers from all over the country are coming to London to join their Metropolitan Police colleagues to line the route.

"We all want to pay honour to the ultimate sacrifice that Keith made."

The Queen gave permission for Pc Palmer's body to rest in Westminster's Chapel of St Mary Undercroft, an honour normally reserved for senior figures.

Ms Thornton said the gesture had had a "tremendous impact" on police as they go about their duty.

She said: "The fact Keith has laid in rest in the Palace of Westminster is a sort of acknowledgement on behalf of the whole country of the sacrifice that he made but also the job that officers do day in, day out."

Full service funerals are normally only held when a police officer or member of staff dies while they are carrying out their duty, Scotland Yard said.

The last full police funeral for a Met officer killed in the line of duty was in October 2013 for Pc Andrew Duncan, who was killed the month before after being hit by a car while checking vehicle speeds in Sutton, south London.

Pc Palmer's name has been added to the roll of honour and remembrance at a ceremony at the National Police Memorial on The Mall, in central London, complete with a guard of honour.

Steve Lloyd, of the Police Roll of Honour Trust, said: "We hope that knowing their loved one's name are to be forever remembered will bring some small comfort to the families of the fallen officers."

Four other innocent people were killed and dozens of others injured in the 82-second atrocity in Westminster on Wednesday March 22, which ended with Masood, 52, being shot dead.

Andreea Cristea, 31, Leslie Rhodes, 75, Kurt Cochran, 54, and Aysha Frade, 44, died after Masood ploughed into pedestrians on Westminster Bridge.
