Fallen hero Keith Palmer is tonight resting in the very place he died trying to protect, ahead of one of the biggest gatherings of British police officers in history.

The 48-year-old’s body has been taken to the Palace of Westminster ahead of his funeral tomorrow – a rare honor that requires the consent of the Queen.

More than 5,000 police men and women are expected to line the road to Palmer's funeral, joined by up to 50,000 members of the public in a touching service for the fallen cop.

But officers have been warned not to wear their uniforms if attending the service, to be held at Southwark Cathedral at 2 p.m. (9 a.m. ET) on Monday.

Instead, changing cubicles have been provided for officers wanting to pay their respects to their colleague.

Palmer was killed when deranged Khalid Masood ploughed through crowds on Westminster Bridge, killing five innocent pedestrians before stabbing the experienced cop outside the Houses of Parliament.
