Thailand’s King Maha Vajiralongkorn has married his long-time bodyguard in a surprise move just days before his coronation.

The Royal Gazette published an announcement saying Suthida Vajiralongkorn na Ayudhya, a former flight attendant, had “legally married” the king in accordance with royal traditions.

“Therefore, he bestows (the title) on General Suthida Vajiralongkorn na Ayudhya from Queen Consort to Queen Suthida as of now,” the announcement said.

The ceremony was overseen by Vajiralongkorn wearing a white uniform in Bangkok’s Dusit Palace Wednesday, according to a broadcast of the announcement, which showed Queen Suthida in a traditional Thai silk dress.
