The Taoiseach is the Prime Minister of Ireland, the head of government. Appointed by the President of Ireland, the nomination comes from Dáil Éireann, the lower house of the Irish parliament. Critically, the Taoiseach must maintain the support of a majority in the Dáil to remain in power. This role is central to the political landscape of Ireland, acting as the chief executive and representative of the government.
