Royal newlyweds the Duke and Duchess of Cambridge are to honeymoon on a Robinson Crusoe island in the Indian Ocean, staying in a £4,000-a-night villa.

According to press speculation the couple will head off to the romantic hideaway for a ten-day holiday. However the exact location is said to be so secret that not even Kate knows yet.

The Duke and Duchess are due to fly out by private jet in mid-May before being taken by helicopter from the mainland to the tropical retreat, according to the Daily Mail.

Two Scotland Yard protection officers conducted security checks of the destination a fortnight ago to ensure it would give the couple sufficient privacy. However the newspaper has not publishing details of the location.

The resort is surrounded by coconut groves, with white sand beaches and crystal-clear turquoise waters that are a sanctuary for sea turtles.

Only a handful of luxury villas are dotted across the island. Hand-crafted out of local wood, each has an open-air bathroom area with sunken bath and shower, a private garden and a wooden deck with freshwater rock pool.

There is a butler on hand in every villa, and a personal chef cooks freshly-caught fish.

The area is perfect snorkelling, kayaking and diving, whilst jet skis is banned to preserve the tranquillity.

A source told the Daily Mail: “It’s one of the most incredible places you will ever visit and Kate will have the time of her life. It’s everything you could want from a honeymoon destination and more – beautiful beaches, tropical seas and complete privacy.

“The prince’s protection officers flew out two and half weeks ago to check it out and their villa has been booked and confirmed.

“It’s a real Robinson Crusoe kind of place. There are some beautiful hikes, but if you can’t be bothered to walk a golf cart will transport you. They will also deliver you a picnic with ice-cold drinks.”

It was widely expected that the couple would be going on honeymoon this week after their wedding on Friday. But at the weekend it was announced that the Duke would be returning to work tomorrow on Anglesey before the trip.

On their return from the honeymoon, the couple will face ten weeks apart as William is being posted to the Falkland Isles to further his helicopter training. This will enable him to be promoted from co-pilot to pilot.

Reports suggest that William is keen to focus on his RAF career, to the extent that he may even be trying to gain enough flying time to be considered for a combat role in Afghanistan, although this is a move that may be blocked due to his status and security concerns.
