She wrote: “I send my best wishes to the thousands of racing professionals and enthusiasts who will join me in celebrating this year’s Royal Ascot.
“In these challenging times, we are once again delighted to welcome the best horses and jockeys from across the world and pay tribute to those who have helped make this race meeting possible.
“This year Ascot will feel different for many, as it is so often a chance for friends, families and colleagues to gather together and enjoy a shared passion.
“I am sure however, that with the valiant efforts of the organisers, owners, trainers and stable staff, it will remain one of Britain’s finest sporting occasions and a highlight of the racing calendar.”
