Bangkok, Dec 5 (IANS): A medical team has asked Thai King Bhumibol Adulyade to cancel plans to include the public as part of his 87th birthday celebrations Friday.

Hundreds of well-wishers wearing yellow shirts have been camping out at Siriraj Hospital and on nearby roads since Thursday to catch a glimpse of the king who was set to make a short trip to the Grand Palace to celebrate his birthday, Bangkok Post reported.

An announcement from the Royal Household Bureau confirmed the cancellation of the ceremony.

"After a medical examination, his majesty's doctors have requested the king not to leave the hospital for an audience at the Amarin Vinitchai Hall," it said.

Both the king and the queen were to hold the audience, and millions awaited the event, thousands at the sites, and others at home.

Despite the cancellation, many well-wishers have flocked into the Grand Palace, where cabinet members, legislators and prominent military and political figures, including Prime Minister Prayuth Chan-ocha and former premier Yingluck Shinawatra, have signed books of birthday wishes for the king.

Many celebrations have been held nationwide, including blood donation, tree plantation, running and bicycling.
