After her graduation from university, Middleton was faced with widespread press attention and was often photographed by the paparazzi. On 17 October 2005, she complained through her lawyer about harassment from the media, stating she had done nothing significant to warrant publicity. Former royal press secretary Dickie Arbiter stated that her treatment by the press drew parallels to the tumultuous experience of William's mother in the early years of her marriage. Media attention increased around the time of her 25th birthday in January 2007, prompting warnings from the Prince of Wales, Prince William, and Middleton's lawyers, who threatened legal action. Two newspaper groups, News International, which publishes "The Times" and "The Sun"; and the Guardian Media Group, publishers of "The Guardian", decided to refrain from publishing paparazzi photographs of her. In 2009, Middleton was awarded £10,000 damages and an apology from the photographic press agency Rex Features Ltd. after she was photographed playing tennis on Christmas Eve while on holiday in Cornwall. In 2010, she pursued an invasion of privacy claim against two agencies and photographer Niraj Tanna, who took photographs of her over Christmas 2009. Middleton obtained a public apology, £5,000 in damages, and legal costs.
