The woman who was in line to be Thailand's next queen has relinquished her royal title.
A statement issued by the palace's Royal Gazette late Friday said that Princess Srirasm, the wife of Crown Prince Vajiralongkorn, had asked permission to give up her royal status.
The palace says 87-year-old King Bhumibol Adulyadej approved the request.
The statement gave no reason for the move, but it comes two weeks after Vajiralongkorn asked the government to strip several members of Srirasm's family of their royally-issued surname after they had been detained in a police corruption probe.
Srirasm has been married to Vajiralongkorn since 2001, and the couple have one son.
Vajiralongkorn is the heir to the throne.
