The Queen is to lie in state for four days at Westminster Hall after her coffin was carried there from Buckingham Palace on a horse-drawn gun carriage.
As thousands of people queued on Wednesday to pay their last respects, Big Ben tolled every minute and King Charles and his siblings, the Princess Royal, the Duke of York and the Earl of Wessex, walked directly to the rear of the coffin, followed by the Prince of Wales, the Duke of Sussex and Peter Phillips, the son of the Princess Royal.
