Royals Queen Elizabeth's Grandson Peter Phillips and Wife Autumn Are Divorcing: It's 'Sad' but 'Amicable' Peter and Autumn Phillips informed the Queen and other members of the family of their decision last year By Simon Perry Published on February 11, 2020 07:52 AM Share Tweet Pin Email Queen Elizabeth‘s eldest grandson Peter Phillips and his wife Autumn have announced that they are divorcing after 12 years of marriage, the couple confirmed Tuesday. “They had reached the conclusion that this was the best course of action for their two children and ongoing friendship,” a spokesman for the couple said. “The decision to divorce and share custody came about after many months of discussions and although sad, is an amicable one. “The couple’s first priority will remain the continued well being and upbringing of their wonderful daughters Savannah and Isla. Both families were naturally sad at the announcement, but fully supportive of Peter and Autumn in the joint decision to co-parent their children.” The pair will share custody of their two daughters, Savannah, 9, and Isla, 7. Their spokesman confirms to PEOPLE that they separated last year and informed the Queen and other members of the family of their decision then. Princess Anne’s son, 42, is the first of his generation of royals to separate from his spouse, adding yet another sad episode for the Queen in recent months.
