TV gardener and presenter Alan Titchmarsh is going behind the scenes at Royal Windsor Horse Show this week (13-17 May) to create an hour-long ITV documentary, focusing on the Royals’ passion for horses.

No date has yet been announced for the televising of the show, whose working title is “All the Queen’s horses with Alan Titchmarsh”.

But it is set to be a celebration of the horse show in every sense, from the splendour of the Royal gardens and grounds of Windsor Castle, to the dedication and achievements of every one involved, including grooms, riders and organisers.

Mr Titchmarsh will also document the competitive participation of the Royal Family at Royal Windsor, highlighting the successes they have enjoyed, along with the Duke of Edinburgh’s official duties as a judge in the carriage driving competitions this year.

And the presenter will not only be rubbing shoulders with the Royals and competitors, but soldiers from the King’s Troop Royal Horse Artillery, as he will host the final performance of the Royal Military Tattoo that takes place each night after the horse show.

Mr Titchmarsh said: “I am incredibly honoured to be given this rare opportunity, particularly when it is held at such a magical place as Windsor Castle.”
