Their own daughter Zara later won a silver medal in the three-day event with the British team at the 2012 Olympics. In 1998, Phillips designed the cross-country venue for the Red Hills Horse Trials, a qualifying event for the Olympics located in Tallahassee, Florida, United States. He is now a regular columnist for "Horse & Hound" magazine. He also remains a leading figure in British equestrian circles, and serves as "Chef d'Equipe" of the United States Eventing Team. Phillips married Princess Anne on 14 November 1973, at Westminster Abbey. They have two children: Peter (born 1977) and Zara (born 1981). It is believed that Phillips declined a peerage from the Queen, which would have allowed his children to use courtesy titles. The Queen bought Gatcombe Park, near Minchinhampton, for the couple as a wedding present. The Prince of Wales is believed to have coined the nickname "Fog" for Phillips, on the grounds that he was "thick and wet". In August 1985, Phillips fathered a daughter, Felicity, as a result of an extramarital affair with New Zealand art teacher Heather Tonkin. Phillips was confirmed as the father as a result of DNA testing during a paternity suit in 1991. In August 1989, the Princess Royal and Phillips announced their intention to separate, as the marriage had been under strain for a number of years. The couple had rarely been seen in public together, and both were romantically linked with other people. They continued to share the custody of their children, and initially announced that "there were no plans for divorce." Meanwhile, Phillips continued to work at the couple's estate at Gatcombe Park. They divorced on 23 April 1992. On 1 February 1997, Phillips married Sandy Pflueger, an American Olympic dressage rider. Their daughter Stephanie was born on 2 October 1997. On 3 May 2012, it was confirmed by Phillips' solicitors that Phillips and Pflueger had separated, intending to divorce. Phillips' personal wealth is thought to be around £15–20 million. The settlement he received when his marriage to Princess Anne ended has been reported as "modest" and as "$3 million".
