Kensington Palace has declined to comment on paparazzi photographs taken of the Duchess of Cambridge while on holiday with Prince George on the exclusive island of Mustique.
The Duchess and her six-month-old baby son were photographed leaving a British Airways plane, thought to have landed on the island of St Vincent.
In the pictures printed by Hello! magazine Kate looked relaxed as she carried her son, who wore a white romper suit and a sun hat.
Kate was accompanied on her trip to Mustique by her younger brother James and the pair were pictured walking down the steps of the plane and across the tarmac.
They were later photographed boarding a smaller aircraft for the final trip to the exclusive island. It has been reported that they joined their parents Carole and Michael Middleton for the winter break.
William remained behind in England where he is almost half way through a 10-week agricultural course being taught at Cambridge University.
