US TV star Meghan Markle joined Britain’s Prince Harry at the altar on Saturday wearing a flowing white dress in front of a star-studded congregation as tens of thousands of fans cheered in the street and millions watched around the world. Harry and the bride’s mother Doria Ragland looked visibly moved and the couple held hands as they exchanged vows in a ceremony led by Archbishop of Canterbury Justin Welby. Harry’s 92-year-old grandmother Queen Elizabeth II and her husband Prince Philip were in attendance as Markle arrived in St George’s Chapel in Windsor Castle, wearing a long white veil and a glittering tiara. Guests at the ceremony included singer Elton John, Hollywood star George Clooney, footballer David Beckham, tennis star Serena Williams and US talkshow host Oprah Winfrey. The 36-year-old bride walked up the aisle on her own before being joined half way by Harry’s father Prince Charles. Her own father pulled out amid a media row that overshadowed the meticulous palace preparations. Tens of thousands of well-wishers cheered as Harry arrived at the church with his brother and best man Prince William, both wearing dark military uniforms. Well-wishers camped overnight to secure the best spots to watch the newlyweds, who will take a ride in an open-topped carriage around Windsor after the ceremony.

The service in St George’s Chapel at noon (1100 GMT) was to mix traditional Church of England ceremony with gospel music, with a choir singing “Stand By Me”, while a US pastor will deliver the main address.

Queen Elizabeth before the wedding conferred the title Duke of Sussex on her grandson Prince Harry, meaning Markle will be known as the Duchess of Sussex. Harry’s ex-girlfriends Chelsy Davy and Cressida Bonas were also among the guests, along with singer James Blunt, US talkshow host James Corden and Markle’s former co-stars from US television series “Suits”. Breaking the barriers Windsor was decked out with flags and bunting, and there was a carnival area on the Long Walk, the sweeping tree-lined avenue down which the royal couple will drive. Thousands of fans arrived at dawn, bearing rugs and picnics, Union Jack flags and royalist paraphernalia, and the prosecco was flowing freely well before the first guests arrived. “We planned to stay in a hotel but we got caught up in all the excitement and we stayed here last night, unprepared,” said Karen Long, from Texas. She said the fact that Markle was mixed-race was a huge moment, saying: “We all wanted to be a princess, we thought we couldn’t and there she is, breaking all the barriers!” Her father Thomas Markle, recovering from a heart operation in Mexico, still appears in the printed order of service. The Emmy Award-winning former television lighting director was caught in a fiasco, posing for staged photographs after complaining of media harassment, then performing several U-turns over whether he would attend.
