The new constitution will be promulgated on Thursday – Chakri Day – in a ceremony to be presided over by His Majesty the King, according to a Royal Household Bureau schedule announced in the Royal Gazette on Monday.

HM King Maha Vajiralongkorn will preside over the ceremony at the Ananta Samakhom Throne Hall starting at 3pm, according to an announcement issued by Prime Minister Prayut Chanocha in line with a royal command.

The ceremony will include members of the Royal Family, privy councillors, Cabinet members, foreign diplomats, National Legislative Assembly (NLA) and Constitution Drafting Commission members, the Supreme Court president, heads of independent organisations, and senior military commanders and civil servants.

At the ceremony, the new charter will be presented to the King for his signature, after which it will be handed to the prime minister.

A court secretary then will read out a royal statement announcing the promulฌgation of the 2017 constitution.

That is to be followed by three rounds of 21gun salutes by the Army, Navy and Air Force.

Deputy Prime Minister Wissanu Kreangam said Monday that after the new charter is promulgated, the NLA and the National Reform Steering Assembly (NRSA) would continue to exist.

The NLA will continue to perform its duties until 15 days before the next general election, while the NRSA will function until the implementation of a new law on reforms, within four months after the charter’s promulgation.
