Prince Georgehad a bashful moment when he arrived in Warsaw, Poland on Monday along with his parents, Prince William and the Duchess of Cambridge, and his sister Princess Charlotte. The youngster timidly retreated into the airplane when he saw the crowd gathered outside before Prince William managed to coax him out onto the plane steps.

Waiting at the bottom of the steps for them were Jonathan Knott, Britain's Ambassador to Poland, his wife Angela, and the diplomat's Polish counterpart in Britain, Arkady Rzegocki, among others. George, who dressed in a checked shirt and navy shorts, eventually followed his father out onto the rolled out red carpet but still appeared a little reluctant to greet the dignitaries lined up to welcome them.

William was seen slightly bending down to talk to his son, which appeared to do the job of settling George's nerves. His two-year-old sister Charlotte seemed to have no reservations, arriving confidently in her mother's arms wearing a red and white floral dress – the colours of the Polish flag.
