Thailand's Their Majesties the King and Queen on Friday presided over the opening ceremony for parliament following the March 24 election.

The ceremony for the king and queen to open the first parliamentary session was held in a hall of the Ministry of Foreign Affairs on Sri Ayutthaya road as the newly-built site of parliament in Kiakkai area has not been readied.

A total of 498 MPs and 250 senators attended the opening ceremony for parliament alongside Prime Minister Prayut Chan-o-cha, members of his cabinet, members of the National Council for Peace and Order and heads of independent agencies.

The king delivered a message to the legislators calling on them to adhere to rules of law, take responsibilities and do the best of their abilities and wisdoms in the course of optimum interests of the country and people and wished them all success and prosperity.

On Saturday, the MPs are scheduled to convene in an auditorium to attend the oath-taking ceremony and vote for a House speaker and deputy House speakers.
