Which royals and celebrity guests will attend?
The guest list is usually kept under wraps until the big day, but members of the royal family are all expected to attend, including Eugenie's grandparents the Queen and Prince Philip. Her proud parents the Duke of York and Sarah, Duchess of York, who remain very good friends despite their divorce, will be top of the guest list, as will Eugenie's cousins, Prince William and Kate, and Prince Harry and Meghan. Zara and Mike Tindall are also expected to make up the royal party, as are Peter Phillips and his wife Autumn.
Prince Charles will attend without his wife Camilla, who has a previous commitment visiting a school. The Queen's cousin, the Duke of Kent, is also confirmed not to attend the evening reception, as he has a dinner in London.
There will also be a few famous faces in the congregation. Fans can hope to see Eugenie's close friend Cressida Bonas, who used to date Prince Harry, and singers Ed Sheeran, James Blunt and Ellie Goulding, who all mix in royal circles. Robbie Williams and his wife Ayda Field are also expected to share some of the spotlight, alongside their daughter Teddy who is a rumoured bridesmaid.
