London attack: PC Keith Palmer lies in rest in Westminster
The body of PC Keith Palmer, killed in the Westminster attack in March, has arrived at the Palace of Westminster ahead of his funeral on Monday.
Lying in rest there is a rare honour and requires the consent of the Queen.
PC Palmer, 48, was guarding the Houses of Parliament when he was stabbed by Khalid Masood, who had driven into crowds on nearby Westminster Bridge.
Five victims died in the attack on 22 March, during which Masood was shot dead by police.
