William visited William Cowley Parchment Makers during his tour of the town, during which the prospect of Harry marrying Meghan was raised.
Paul Wright, the store’s general manager, told him: ‘If Prince Harry marries Meghan then his certificate will be in our vellum.’
William simply burst out laughing in response to the comment, with Mr Wright later explaining: ‘He just laughed – a nice laugh.’
Under the Royal Marriages Act 1772, all descendants of George II must obtain the sovereign’s agreement before they wed, otherwise the marriage is invalid.
The Instrument of Consent is an elaborate document made from vellum, usually calf skin, proclaiming the monarch’s approval of a marriage and bearing a large red wax Great Seal of the Realm.
Meanwhile, William also said that George, four, is already fed up with going to St Thomas’s School in Battersea.
