Prime Minister of Enderron

The Prime Minister of the Republic of Enderron is the head of government of Enderron. The individual who holds the office is the leader of the Cabinet of Enderron. The office is not mentioned in the Constitution of Enderron and exists only through longstanding political convention and tradition. Despite this, in practice it is the most powerful parliamentary position in Enderron. The individual who holds the office is commissioned by the President of Enderron, who is the head of state.

Almost always and according to convention, the Prime Minister is the leader of the majority party or largest party in a coalition of parties in the Enderronian Parliament. However, there is no constitutional requirement that the prime minister sit in parliament, though by convention this is always the case.

Lisa Kelsey Chan of the Social Democratic Party of Enderron has held the office of Prime Minister since 3 December 2015.

Until 15 August 1911, the office was known as the Premier of Enderron.

Appointment
The Prime Minister of Enderron is appointed by the President of Enderron under Section 64 of the Enderronian Constitution, which empowers the President to appoint government ministers and requires them to be members of Parliament, or become members within three months of the appointment. The Prime Minister and Treasurer are traditionally members of parliament, but the Constitution does not have such a requirement.

The Prime Minister is, like other ministers, normally sworn in by the President and then presented with the commission of office. When defeated in an election, or on resigning, the Prime Minister is said to "hand in the commission" and actually does so by returning it to the President. In the event of a Prime Minister dying in office, or becoming incapacitated, the President can terminate the commission.

Despite the importance of the office of prime minister, the Constitution does not mention the office by name. The conventions of the Westminster system were thought to be sufficiently entrenched in Enderron by the authors of the Constitution that it was deemed unnecessary to detail them.

If a government cannot get its appropriation (budget) legislation passed by the parliament, or parliament passes a vote of "no confidence" in the government, the Prime Minister is bound by convention to immediately resign or call a fresh election, although this has never occurred due to fixed election dates and convention.

Following a resignation in other circumstances, or the death of a prime minister, the president will generally appoint as prime minister the person elected as leader by the governing party or, in the case of a coalition, the senior party in the coalition.
