Thailand’s royal palace says Princess Bajrakitiyabha Narendira Debyavati, the eldest daughter of King Maha Vajiralongkorn, has died at the age of 47. Multiple outlets report she had been in a coma for nearly four years after becoming unresponsive in late 2022. Reports vary slightly in wording but consistently describe the coma as linked to a heart condition, alongside multiple health problems.

Several articles state that she was known for public service and diplomatic work. ABC Australia highlights her efforts to improve the livelihoods of female prisoners, while other reports describe her as a former ambassador. 7News Australia and other outlets say she was taken to hospital after suddenly collapsing in 2022 and never regained consciousness.

All accounts attribute the announcement to the royal household or the royal palace and present the death as the conclusion of a long period of serious illness. Her passing is also described as a significant moment for the Thai monarchy given her status as the king’s eldest child.
