The King and Queen Consort will leave Buckingham palace about 10.20am, travelling to Westminster Abbey to be crowned by the Archbishop of Canterbury during a coronation ceremony dating back centuries.
Royal fans with Union flags and crowns could be seen on trains and in Tube stations from just after 4.30am. Metropolitan police and military police officers patrolled the route from Victoria to Westminster from the early hours on Saturday.
The event will bring together around 100 heads of state, kings and queens from across the globe, celebrities, everyday heroes and family and friends of the couple, with Charles’ estranged son the Duke of Sussex expected to attend.
Invited guests include David and Victoria Beckham, musician Lionel Richie, French President Emmanuel Macron, King Willem-Alexander and Queen Maxima of the Netherlands, Prime Minister Rishi Sunak and US First Lady Jill Biden but her husband President Joe Biden will not be attending.
The day will be a display of pomp and pageantry, with the nation’s Armed Forces promising a “spectacular” event when the King and Queen process through the streets of the capital.
