Thai princess next in line to throne 'suffers heart attack while out running'

A Thai princess, who is the next in line to the throne, is reportedly “unlikely to recover” after suffering a heart attack.

King Vajiralongkorn is understood to have flown by helicopter to be with his daughter.

Princess Bajrakitiyabha of Thailand, 44, was reportedly out running with her dogs in the Khao Yai national park, in the northeast of Bangkok, when she collapsed.

CPR was carried out “for more than an hour”, according to journalist Andrew MacGregor Marshall, and sources have said that the princess could not be revived.

It is claimed she has been put on an oxygen machine and it is thought she is being artificially kept alive.

Mr MacGregor Marshall tweeted : “Some sources are saying that despite CPR being carried out for more than an hour, there was no response and she has been put on an ECMO machine, which basically means she is dead but being artificially kept alive.”

Three large military helicopters were also reportedly seen returning to Bangkok from Khao Yai unusually late at night on Wednesday.

It is thought that she was first taken to Pak Chong Nana Hospital where CPR was unsuccessful and that was were the King also went via helicopter to see his daughter.

From there she was taken to Bangkok Hospital for the ECMO treatment with witnesses reportedly seeing a hospital helicopter flanked by two military choppers.

“Royal sources say the prognosis for the princess is very grim and it’s very unlikely she will ever recover. But she could potentially be kept artificially alive via ECMO for weeks or even months while the regime figures out what to do," tweeted Mr MacGregor Marshall.

"These events have huge repercussions for the Thai monarchy because it was assumed Bajrakitiyabha would be the next monarch, or would be regent for her younger half-brother Dipangkorn who has autism and will not be able to reign alone."

There has been no official news on the health of the princess despite many hours now of rumours and speculation on social media.

The Mirror UK has contacted the Thai Royal Family for comment.
