"Thailand's Princess Bajrakitiyabha has passed away in a hospital after being in a coma for over three years, the royal palace announced on Friday. She was 47 years old.
The princess was suffering from an abdominal infection and "her condition continued to worsen", the palace said.
Bajrakitiyabha was the eldest daughter of Thailand's king, Maha Vajiralongkorn.
In December 2022, while on a visit to the northeastern province of Nakhon Ratchasima, the princess suddenly lost consciousness due to a heart condition.
She was flown by a helicopter to the capital Bangkok for treatment and had been hospitalized since then.
The palace said she "passed away peacefully" on Thursday evening.
Her body will lie in state at the Grand Palace in Bangkok, the royal palace said, adding that the funeral would be held "with the highest honors according to royal tradition."
The Thai government is also expected to declare a period of national mourning. "
Oh, what a sad way to go. I'm sure the family is relieved that she's been released from a 3-year coma, but devastated that she never regained consciousness.
