Family, friends and colleagues of royal bride Lady Gabriella Windsor and groom Thomas Kingston have begun arriving for their wedding.

Guests were ferried in vintage buses close to St George’s Chapel at Windsor Castle and then walked down the hill to take their seats for the ceremony.

The Duke of Sussex left his wife and baby son Archie at home to attend the wedding and arrived with his uncle and aunt, the Earl of Wessex and the Princess Royal, who was joined by her husband Vice Admiral Timothy Laurence.

The Duke of York arrived by car with his ex-wife Sarah, the Duchess of York, and their daughter Princess Beatrice and her boyfriend Edoardo Mapelli Mozzi.

Pippa Middleton and husband James Matthews were also among those arriving and another famous face was Downton Abbey creator Julian Fellowes.

The society event was a parade of hats, dresses and men in morning suits as everyone waited for the ceremony to begin at noon, conducted by Dean of Windsor the Right Rev David Conner.

It is the third royal wedding in the 15th-century venue in less than a year after the star-studded nuptials of the Duke and Duchess of Sussex last May and Princess Eugenie and Jack Brooksbank in October.
