Prince George becomes star of Kensington Palace party after greeting the leader of the free world while wearing his monogrammed dressing gown and slippers

The Obamas visited the palace for an informal dinner with Prince William, Kate Middleton and Prince Harry - just hours after the U.S. President's controversial intervention in the Brexit debate. But it was two-year-old prince who stole the limelight after pictures emerged of George shaking hands with the leader of the free world wearing his all-white nightwear (left) and playing on his rocking horse (right). Along with Prince Harry, William and Kate opened the doors of their 22-room private apartment - number 1A - to Mr and Mrs Obama, after the couple had lunched with the Queen at Windsor Castle. It is the first time that any of the young royals have entertained a head of state privately and the most significant event they have ever hosted at Kensington Palace.
