LONDON - Britain’s 2022 Royal Windsor Horse Show will feature a Queen Elizabeth Platinum Jubilee celebration with hundreds of horses and 1,000 performers marking her 70th anniversary on the throne.

Queen Elizabeth, the longest-reigning monarch in British history, ascended the throne on Feb 6, 1952 on the death of her father George VI

The 90-minute military, musical and equestrian spectacular from May 12-15 will culminate in a live-broadcast final show before the Queen, a horse lover. “Platinum Jubilee Celebration: A Gallop Through History,” on the grounds of Windsor Castle, will involve more than 10 nations the monarch has toured on state visits.

“We are going to be telling a story not just of the Queen and her 70 years, but the whole history from Queen Elizabeth, the first era to now,” said Simon Brooks-Ward, director and producer of Platinum Jubilee Celebration, in an interview at Buckingham Palace, during a media launch on Tuesday.
