List of Prime Ministers of Thailand
The Prime Minister of Thailand is the head of government of the Kingdom of Thailand. The prime minister is also the chairman of the cabinet of Thailand and represents the government at home and the country abroad.
The post of prime minister has existed since 1932, after a bloodless revolution forced the absolutist King Prajadhipok to grant for the people of Siam their first constitution. Under the newly established constitutional monarchy, the first prime minister of Siam was Phraya Manopakorn Nititada. At first, the office was called the President of the People's Committee, it was later changed to Prime Minister of Siam when the king deemed it too communistic.
Constitutionally the prime minister is required to be a member of the lower house of the National Assembly. He must also gain their approval through a resolution before an official appointment by the king can take place. As a result, the prime minister might succumb to a vote of no confidence and removal in the House. However, this has never happened up to date.
Throughout the post's existence it has mostly been occupied by military leaders from the Royal Thai Army, three holding the rank of field marshal and seven the rank of general. The post of prime minister is currently held by General Prayut Chan-o-cha, who was formally appointed to the office on 24 August 2014. Previously he was the de facto head of government as leader of the National Council for Peace and Order, since the coup d'état on 22 May 2014.
Note: The list includes leaders of military juntas and acting prime ministers. However, they are not counted in the official list as provided by the Royal Thai Government
