Canadian Prime Minister Justin Trudeau and his wife, Sophie Gregoire Trudeau, announced Wednesday that they are separating after 18 years of marriage.

The two said in statements posted on Instagram that they made the decision after “many meaningful and difficult conversations.” A statement from the prime minister’s office said they both have signed a legal separation agreement.

Trudeau, the 51-year-old scion of one of Canada’s most famous politicians, was sworn into office in 2015. Sophie Trudeau is a former model and TV host. The couple were married in 2005. Together, they brought star power to the prime minister’s office and appeared in the pages of Vogue magazine.

They have three children, 15-year-old Xavier, 14-year-old Ella-Grace and 9-year-old Hadrien.

The first lady has played a less visible role in recent years, rarely traveling with the prime minister on official trips. The two were seen together publicly at Canada Day events in Ottawa last month.

“They remain a close family, and Sophie and the prime minister are focused on raising their kids in a safe, loving and collaborative environment,” the statement from Trudeau’s office said. “The family will be together on vacation, beginning next week.”

His office requested respect for their privacy.

Justin Trudeau and Sophie Gregoire met as children when she was a classmate of his youngest brother, Michel, and they reconnected as adults when they co-hosted a 2003 charity gala.

Trudeau is the second prime minister to announce a separation while in office.

His father, Pierre Trudeau, and mother, Margaret Trudeau, separated in 1979 and divorced in 1984 during the elder Trudeau’s final year in the prime minister’s office.

Justin Trudeau channeled the star power of his Liberal icon father when he first won office in 2015. Scandals, voter fatigue and economic inflation have taken a toll on his popularity after eight years in power.
