The 69-year-old royal will be joined during the visit by Penny Mordaunt, the new international development secretary.

But the UK has so far committed £62 million to the relief effort following Irma and Maria and has promised to match public commitments to the British Red Cross Appeal up to £3 million.

A spokeswoman for Mordaunt said: “The international development secretary will also be joining the visit to see first-hand the impact of the UK government’s humanitarian relief efforts that were monumental in getting the islands open for business and tourists following the hurricanes.”
