The Queen is to lie in state for four days at Westminster Hall after her coffin was taken 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.
The oak casket was placed on a raised catafalque in the centre of the hall. After a service led by the archbishop of Canterbury, bodyguards and officers stood watch around the casket, which was illuminated by four tall candles.
The ceremony was attended by the prime minister, Liz Truss, the Labour leader, Keir Starmer, and the leaders of other political parties and high commissioners from realms for whom the Queen was head of state.
