More than 100million people around the world are about to watch the historic first coronation of a British monarch in 70 years – with an estimated 2million people on the streets of London to watch history unfold.
The monarch had been heir since the age of three, and is now ready to finally embrace his day of destiny with the woman he loves by his side.
His family, including Prince Andrew and Princess Anne, enjoyed a dinner at Mayfair club Oswald’s on Friday night. Mike and Zara Tindall were out until 2am.
Prince Harry flew in from Los Angeles for his 24-hour trip. It emerged on Friday night he has been relegated to the third row in the Abbey with other non-working royals.
