The queen’s guards regiments performed a faultless spectacle repeated every year to mark the monarch’s official birthday.
Because of the better weather in June, the celebrations of the Queen’s birthday, which is on April 21, are traditionally delayed until the second Saturday in June.
William, in the uniform of the Irish Guards, rode directly behind the carriage of the queen – his grandmother – and Prince Philip, who celebrated his 90th birthday Friday.
Catherine, the former Kate Middleton, watched from a building looking on to Horseguards Parade, together with her mother-in-law, Camilla, the Duchess of Cornwall.
After the Duchess of Cambridge’s first public engagement with her new title on Thursday – a lavish dinner with charitable giving and considerable wealth on display – this was more familiar royal territory, says BBC royal correspondent Peter Hunt.
