The Queen, Prince Philip, the Duke of Sussex, Princess Anne and the Middletons watched today as royal bride Lady Gabriella Windsor married Thomas Kingston in the biggest society wedding of the year so far.

Prince Harry was at St George's Chapel in the grounds of Windsor Castle just 12 days after the birth of Archie, his first son with wife Meghan - and on the eve of their first wedding anniversary.

The Queen was joined by Prince Philip as the Duke of Edinburgh made a rare public appearance following his retirement two years ago.

Other royals at the chapel today included Sarah, Duchess of York with her ex-husband Prince Andrew and their daughter Princess Beatrice with her boyfriend Edoardo Marpelli Mozzi.
