Prince Harry leaves Meghan at home with baby Archie as he attends Lady Gabriella Windsor's wedding to Tom Kingston

Prince Harry has arrived at the wedding of Lady Gabriella Windsor with Lady Frederick Windsor.

The Duchess of Sussex has chosen to stay home home with newborn Archie.

Prince Harry entered the chapel accompanied by Princess Anne, Sir Timothy Laurence, the Earl of Wessex and Princess Alexandra.

They were followed by the Duke of York and Sarah Ferguson, the Duchess of York, who is wearing a peach-coloured dress and matching hat.

Lady Gabriella, 38, is marrying her financier boyfriend Thomas Kingston, 40, at St George’s Chapel at Windsor Castle, almost one year after the Duke and Duchess of Sussex wed at the same venue.

Princess Eugenie and Jack Brooksbank also chose St George’s Chapel for their wedding in 2018.

The Queen will lead members of the royal family at the ceremony, but the Duke of Cambridge will instead be watching the FA Cup Final in his role as President of the Football Association.

Lady Gabriella Marina Alexandra Ophelia Windsor – also known as 'Ella' – is the daughter of Prince and Princess Michael of Kent and is the Queen's first cousin once removed.

She is the 52nd in line to the throne following the birth of Archie Mountbatten-Windsor on May 6.

Lady Gabriella, who turned 38 in April, is believed to be the oldest first-time royal bride in recent years.

Her older brother Lord Frederick 'Freddie' Windsor is married to Ms Winkleman - who plays 'Big Suze' - and the pair have two children Maud, five, and Isabella, three.

Her father, Prince Michael, is the Queen’s cousin and regularly represents the Royal family at public engagements.

Her mother, Princess Michael, is an author who has been nicknamed “Princess Pushy” for her forthright views
