Their Majesties the King and Queen will preside over the opening of parliament on May 24 at Vithes Samosorn Hall, according to the cabinet's secretariat office.
Sorasak Pianvech, House of Representatives secretary-general, said he has received a letter from the cabinet's secretariat office saying Their Majesties will officially open parliament at 3pm on May 24, following a royal decree announcing that parliament will convene on May 22.
According to Mr Sorasak, after parliament has officially convened, the Senate will hold a meeting to choose the Senate speaker and deputies while the House of Representatives will select the House Speaker and deputies the following day.
Under Section 121 of the constitution, parliament must convene its first meeting within 15 days of at least 95% of the poll results being announced. The EC endorsed 498 MPs of the total 500 last week.
When the House speaker and the Senate speaker are royally endorsed, the House speaker, who serves as the president of the parliament, will decide when a joint sitting of MPs and senators will be held to choose a prime minister.
