In February 2013, "Chi" published the first photos of Catherine's exposed baby bump, taken during her vacation on the private island of Mustique. The British press refused to publish the paparazzi shots. While the Duchess was visiting the Blue Mountains in Sydney, a picture was taken of her bare bottom as her dress blew up. Many newspapers outside the UK published the picture. On 14 August 2015, Kensington Palace published a letter detailing what it stated were the "dangerous" and invasive efforts of the media to get paparazzi pictures of Prince George and Princess Charlotte. Jason Knauf, communications secretary to the Cambridges, wrote the letter to media standards organisations in various countries.
