Queen Elizabeth II's coffin has arrived at Buckingham Palace, after being transported from west London's RAF Northholt airbase by car.

The Queen's family received the coffin on its arrival at the palace, where it will rest in the Bow Room overnight.

The coffin was transported from Edinburgh earlier on Tuesday on a C-17 Globemaster transport plane, Air Chief Marshal Sir Mike Wigston told Sky News Tuesday in an on-camera interview.

It's a "heavily used aircraft, it carried the majority of the 15,000 people that we evacuated from Kabul last summer," said Wigston.

"And, since then, it's been involved in airlifting humanitarian aid and lethal aid nodes to support Ukraine," he added.Princess Anne accompanied the Queen on her final flight. The deceased monarch's only daughter, Anne was also the only one of the Queen's four children to accompany her coffin from Balmoral Castle to Edinburgh on Monday
