The President is therefore an MP, usually from the majority party in the House of Representatives. The Speaker or the President is elected at the beginning of a House session immediately after an election, there are no term limits for the office. The current incumbent is Somsak Kiatsuranont of the Pheu Thai Party who took office on 3 August 2011, succeeding Chai Chidchob
