Following the 11am ceremony, Eugenie and Jack will make a short carriage procession to St George's Hall, where traditional wedding breakfast attended by all guests will be hosted by Queen Elizabeth and Duke of York.
A select 400 guests have also been invited to a champagne evening party at the family home, Royal Lodge in Windsor Great Park.
According to Mail On Sunday, Sarah Ferguson, Duchess of York, is ‘terrified’ about the prospect of coming face-to-face with her former father-in-law, the Duke of Edinburgh.
‘He absolutely adores Eugenie. He can’t stand up for very long, which makes church services hard work, and he can’t stand Fergie, but he wants to see Eugenie married and, if he is fit enough to be there, he will be there. It won’t be easy.
'Philip and Sarah will be in relatively close proximity to each other and Sarah’s very nervous about it. People have been giving her some friendly advice. As long as she doesn’t go over the top on the day, it should all be fine.’
According to the publication, the York's have reportedly spent £100,000 on a three-course dinner for guests, organised by firm Bentey's.
