Queen Elizabeth died at Balmoral Castle on Thursday at the age of 96. Her coffin was transported to Edinburgh earlier this week, where the public were invited to pay their respects at St Giles' Cathedral. It was flown to London on Tuesday evening.
Prince Harry, Prince William, King Charles, and his siblings – Princess Anne, Prince Edward, and Prince Andrew – led a procession from Buckingham Palace to Westminster Hall, where the Queen's body will lie in state until her funeral on Monday.
The procession will travel via Queen's Gardens, The Mall, Horse Guards and Horse Guards Arch, Whitehall, Parliament Street, Parliament Square, and New Palace Yard before arriving at Westminster Hall, according to a Buckingham Palace press release sent to Insider.
Camilla, Queen Consort, and Kate Middleton, the Princess of Wales, as well as Meghan Markle and Sophie, Countess of Wessex, were pictured traveling there by car, according to BBC News.
Camilla and Middleton were pictured traveling in the same vehicle, and both were seen wearing all-black morning outfits with silver jewelry.
After the coffin procession, there will be a short service conducted by the Archbishop of Canterbury and attended by the royal family, the press release states.
Members of the public will be able to visit the Queen's coffin from Wednesday, and hundreds of thousands of people are expected to pay their respects. BBC News previously reported that lines could last up to 30 hours.
