The royals are later expected to attend the Platinum Jubilee pageant at Buckingham Palace, which features a three-kilometre parade led by the Gold State Coach that carried the Queen to and from her coronation in 1953.
Artists including Ed Sheeran and Sir Cliff Richard are set to perform at the event, which is the culmination of the Queen's Platinum Jubilee celebrations.
