The Tánaiste is appointed by the president of Ireland on the advice of the Taoiseach. The current office holder is Simon Harris, TD, who was appointed on 23 January 2025.

History

Under the Gaelic system of tanistry, the word (plural , , approximately ) had been used for the heir of the chief () or king (). The word was adopted in the 1937 Constitution of Ireland as the title for a member of the government nominated by the Taoiseach to act in their place as needed during periods of the Taoiseach's temporary absence.

Tánaiste is the official title of the deputy head of government in both English and Irish, and is not used for other countries' deputy prime ministers, who are referred to in Irish by the generic term , , approximately . The Irish form, , is sometimes used in English instead of "the Tánaiste".

Overview The office was created in 1937 under the new Constitution of Ireland and replaced the previous office of Vice-President of the Executive Council, which had existed under the Constitution of the Irish Free State, and which was first held by Kevin O'Higgins of Cumann na nGaedheal from 1922 to 1927.

The Taoiseach nominates one member of the Government to the office who is required to be a member of Dáil Éireann.Article 28.7.1° of the Constitution of Ireland. The nominee then receives their seal of office from the President of Ireland in recognition of the appointment. The Tánaiste acts in the place of the Taoiseach during a temporary absence. In the event of the Taoiseach's death or permanent incapacitation, the Tánaiste acts as Taoiseach until another is appointed.Article 28.6.2° and 28.6.3° of the Constitution of Ireland. The Tánaiste is, , a member of the Council of State. The Tánaiste chairs meetings of the government in the absence of the Taoiseach and may take questions on their behalf in the Dáil or Seanad.

Aside from those duties, the title is largely honorific as the Constitution does not confer any additional powers on the office holder over and above the other members of the Government. In theory, the Tánaiste could be a minister without portfolio, but every Tánaiste has in parallel held a ministerial portfolio as head of a Department of State. The Department of the Taoiseach is a Department of State, but there is no equivalent for the Tánaiste. Dick Spring in the Rainbow Coalition (1994–1997) had an official "Office of the Tánaiste", but other parties have not used that nomenclature. Under Spring, Eithne Fitzgerald was "Minister of State at the Office of the Tánaiste", with responsibility for co-ordinating Labour policy in the coalition.

Under a coalition government, the Tánaiste is typically the leader of the second-largest coalition partner, just as the Taoiseach is usually leader of the coalition's senior partner. However, during the coalition governments in 1989–1992 and 2007–2011, the position was held by Fianna Fáil's deputy leader, rather than the leader of a junior partner. As part of a rotating Taoiseach agreement since 2020, the role of Tánaiste gained increased prominence and responsibility in coordinating and Government policy as it was held by Leo Varadkar for the first half of the Government's term in office prior to his appointment as Taoiseach and Micheál Martin in the second half.

The office of Tánaiste is as yet the highest government rank attained by a woman Minister.

Four Tánaistí later held the office of Taoiseach: Seán Lemass, Bertie Ahern, Brian Cowen, and Leo Varadkar (his second term as Taoiseach). Varadkar is also one of three Tánaistí, with Micheál Martin and Simon Harris, to have previously held the office of Taoiseach before becoming Tánaiste. Two Tánaistí were later elected as President of Ireland: Seán T. O'Kelly and Erskine H. Childers.
