So the opening day of King Charles III's Coronation has come to an end.

He and the queen consort have had a busy-ish day. They’ve been at the final rehearsals for tomorrow’s ceremony before Charles, joined by William and Kate, met with well-wishers on The Mall.

Charles then met with leaders of the Commonwealth before hosting dignitaries from around the world at Buckingham Palace.

But the real action starts tomorrow. Charles’ Coronation will start at 11:00 BST at Westminster Abbey before he and Camilla, the Queen Consort, pass thousands and thousands of fans on their way back to the palace where they will get a fly past from the Red Arrows and other aircraft.

But it’s not all celebrations here in London. The Republic anti-monarchy group is planning a demonstration in Trafalgar Square and around the country. (BBC)
