The Queen arrived back in London on Tuesday after making her final journey from Scotland. Her coffin was transported by plane to RAF Northolt, accompanied by her devoted daughter, Princess Anne.

On Wednesday, a procession will take place to move the late monarch to Westminster Hall, where the Queen will lie in state for four days.
The coffin will leave Buckingham Palace at 14:22. Crowds will be able to watch as the cortege makes the journey through central London – along Queen’s Gardens, The Mall, Horse Guards and Horse Guards Arch, Whitehall, Parliament Street, Parliament Square and New Palace Yard.
The procession will include the King and members of the Royal Family. Guns will be fired at Hyde Park and Big Ben will toll to mark the solemn event.
