"The ceremony will be followed by a private reception, given by The Queen, in the gardens of Buckingham Palace."
Express.co.uk is now reporting that the pair wanted to say their vows abroad, but had to scrap the plans due to Philip and Queen Elizabeth's health conditions.
The report comes weeks after Bea's grandfather spent four days in hospital over Christmas. Meanwhile, Her Majesty scrapped a royal engagement in January due to health issues.
This left Bea and Edo with no other option but to hold the wedding in the UK.
Now a royal insider has revealed to The Daily Telegraph that her father, the Duke of York, will take part in the wedding after missing the celeb-filled engagement party, because of the uproar surrounding his friendship with deceased paedophile, Jeffrey Epstein.
The wedding will not be broadcast on television like her sister Princess Eugenie's wedding to Jack Brooksbank.
