Princess Charlotte was seen schooling little brother Prince Louis on royal etiquette as they made their carriage procession debut at the Queen's Birthday Parade.

The Cambridge family and the Duchess of Cornwall lead the procession towards Horse Guards Parade in the top carriage as part of the Platinum Jubilee celebrations, marking the Queen's 70 years of public service.

George, 8, Charlotte, 7, and Louis, 4, were photographed waving to spectators on The Mall as the crowd erupted into applause. Enthusiastic Louis continued to wave once his older siblings had stopped, prompting Charlotte to gently push his arm down on his lap to signal that the waving was officially over. He stopped briefly, before starting up again solo, clearly enjoying all the excitement and pomp and pageantry of the special occasion.

The adorable moment was caught on camera as part of the BBC's coverage of the jubilee and shared on social media.

All three young royals were decked out in blue and white, while Kate looked elegant in a white Alexander McQueen dress with a navy blue and white hat by Philip Treacy.

Behind the Cambridges and Camilla were Prince Edward and Sophie, Countess of Wessex with their children, followed by the Duke and Duchess of Gloucester and Sir Tim Laurence.

Prince Charles, Prince William and the Princess Royal arrived on horseback, and Charles deputised for his mother, who did not take part in the parade, by taking the salute.

The colour was trooped by the 1st Battalion, Irish Guards, and more than 1200 officers and soldiers from the Household Division put on a display of military pageantry on Horse Guards Parade, together with hundreds of Army musicians and around 240 horses.

Prince Harry and Meghan and their children Archie and Lilibet joined Harry's family in Horse Guards Parade before being seated with other royals at Duke of Wellington's former office to watch the proceedings from inside.

The Queen later saluted from Buckingham Palace's balcony surrounded by fellow senior royals.
