Prince Harry secretly moves in with Kate and Wills at Kensington Palace

London: Prince Harry, who is back from Jamaica after his royal tour as part of the Queen’s Diamond Jubilee, has secretly moved in with his newly-wed brother and sister-in-law at their new official residence, Kensington Palace.

The 27-year-old royal shipped his belongings over from his old room at Clarence House last week, shortly after returning from his hugely successful first solo tour.

Far from reminding the prince that “three’s a crowd”, the Duke and Duchess of Cambridge have welcomed Harry with open arms, the Daily Mail reported.

William and Catherine currently live in Nottingham Cottage, which is situated in the north of the palace grounds.

Harry, 27, has moved into what is jokily being referred to as the “royal bedsit” in a residential wing nearby, a modest one-bedroom former staff apartment with a small lounge, kitchenette and bathroom.

The apartment has been empty for some time meaning the third-in-line-to-the-throne, who used to share a suite of rooms with his brother at Clarence House, their father’s official London residence, was able to move in straight away.

When William and Catherine eventually move into Princess Margaret’s old apartment, which will become their permanent Kensington Palace base, towards the end of next year, Harry will then take over their cottage.

“He has been really looking forward to getting his own place after living with his father for so long. Understandably he wants to spread his wings,” a source said.

“Some people might find it strange that he is moving in next door to his brother and sister in law, but the three of them get on brilliantly and love spending time together. Prince Harry adores his brother and says Catherine is the sister he never had.

“They were so enthusiastic about the idea of living together that when it emerged that this apartment was free, Harry moved his gear in as soon as he could after returning from Brazil.’ A palace source described the prince’s apartment as ‘surprisingly modest’.

“It’s a small, one-bedroomed apartment. Not what you might normally expect. But he is very happy with the arrangement,” the source added.

Details of the move are set to emerge in a new documentary on Harry to be broadcast on CNN this Friday.
