But while many special guests were partying into the early hours of Sunday morning, radio presenter Roman Kemp, who hosted the BBC's coverage of the celebration, revealed the surprising way that Buckingham Palace shut down the after party towards the end of the night.

Chatting to Kirsty Young during the BBC's coverage of the Platinum Pageant on Sunday, the 29-year-old presenter revealed that the Palace switched the lights on in the early hours to encourage guests to go home.
"What I can't believe is at an after party at Buckingham Palace, I'm going to say this," started Roman. "They turned the lights on to make everyone leave, that's the funny thing."

"I didn't stay that late," confessed Kirsty Young.

Roman continued: "It got so late and you know when you go to a nightclub, I literally went from under-18s Destiny nightclub in Watford where they turn the lights on at the end to still turning lights on at the end at Buckingham Palace."
The special event saw a crowd of 22,000 people, including thousands of key workers, flock to Buckingham Palace for live performances, while over 11 million people tuned in to watch the show at home.
Many senior royals, including Prince Charles and the Duchess of Cornwall, as well as the Duke and Duchess of Cambridge, alongside two of their children, Prince George and Princess Charlotte, were in attendance, enjoying the spectacle from the royal box.
