Maha Vajiralongkorn

King Bhumibol Adulyadej died on Thursday and the crown prince wants more time to mourn his father.

Former Prime Minister Prem Tinsulanonda is standing in as regent.

Current Prime Minister Prayuth Chan-ocha sought to reassure Thais about the succession in a TV address on Saturday, saying they should not worry.

This issue was discussed when Crown Prince Vajiralongkorn summoned the regent and Gen Prayuth for an audience, according to Gen Prayuth.

The prince's decision was relayed to the media by Prime Minister Prayut Chan-o-cha, after an extraordinary meeting at Thailand's National Assembly.

"We are at the most important time. We need to do everything smoothly. I met Crown Prince today and he has been aware that he has been appointed as a successor up until now.

"But he needs time to jointly mourn with Thai people."

Prince Vajiralongkorn was named as successor to the throne on December 28, 1972.
