Princess Eugenie and her fiance Jack Brooksbank “have been touched by the many good wishes they have received in the run up to their wedding”, Buckingham Palace has said.

The couple, who will wed on October 12, have released details of their nuptials as the countdown begins to their big day.

The service will take place at Windsor Castle’s St George’s Chapel at 11am, with the Dean of Windsor, David Conner, officiating and the Archbishop of York, John Sentamu, leading the prayers.

Like the Duke and Duchess of Sussex’s wedding, held at the same chapel, 1,200 members of the public have been invited into the castle grounds to enjoy the occasion.

The palace said that after receiving more than 100,000 applications, invitations had now gone out to the lucky group chosen.

Buckingham Palace said: “Her Royal Highness Princess Eugenie and Mr Jack Brooksbank have been touched by the many good wishes they have received in the run up to their wedding on October 12 2018.

“They are looking forward to celebrating with their family, friends, and members of the public within the castle grounds and in Windsor.”

Other guests in the castle grounds will include representatives of charities and organisations supported by the couple, including the Royal National Orthopaedic Hospital, the Teenage Cancer Trust, the Salvation Army and the UN Trust Fund to End Violence Against Women.

Children from two local schools both attended by the princess, St George’s and Coworth Flexlands, will be present, alongside members of the Windsor community, residents of Windsor Castle and a number of Royal Household staff.

After the service the newlyweds will ride in a carriage through the streets of Windsor as Harry and Meghan did, but their route will not be as long.

Crowds are expected to watch the couple as they travel along Castle Hill, High Street and Park Street.

Following the carriage procession the Queen will give a reception at Windsor Castle for the couple and their guests.
