The 2007 Irish general election took place on Thursday, 24 May after the dissolution of the 29th Dáil by the President on 30 April, at the request of the Taoiseach. The general election took place in 43 parliamentary constituencies throughout Ireland for 166 seats in Dáil Éireann, the lower house of parliament, with a revision of constituencies since the last election under the Electoral (Amendment) Act 2005.

While Fine Gael gained 20 seats, Fianna Fáil remained the largest party. The election was considered a success for Fianna Fáil; however, Fianna Fáil's junior coalition partners in the 29th Dáil, the Progressive Democrats, lost six of their eight seats.

The 30th Dáil met on 14 June to nominate a Taoiseach and ratify the ministers of the new 27th Government of Ireland. It was a coalition government of Fianna Fáil, the Green Party and the Progressive Democrats initially supported by four Independent TDs. It was the first time the Green Party entered government.

Election date and system

On 30 April 2007, President Mary McAleese dissolved the 29th Dáil on the request of the Taoiseach, Bertie Ahern. The election date was officially set as 24 May 2007; the 30th Dáil would convene on 14 June 2007 at which stage the Taoiseach would be nominated and the rest of the Government approved for appointment by the President. Official campaigning began as soon as the announcement had been made.

Current statute requires that the Dáil be dissolved within five years after its first meeting (6 June 2002) following the previous election and the election must take place not later than thirty days after the dissolution. The Taoiseach allowed the 29th Dáil to near the completion of its five-year term before seeking a dissolution. After the 2002 general election he commented that his prior confirmation of this policy had caused problems in the last year of his government. There was speculation in 2005 that he might have moved to dissolve parliament early to catch the opposition off guard, although this did not transpire.

In 2005, in anticipation of the election date, the parties began candidate selections and from mid-2005 some members of the 29th Dáil announced their retirement plans.

A statement by Minister of State for Children Brian Lenihan in November 2006 suggested that the election would take place in May 2007, which would be the case. In December 2006, Bertie Ahern stated unambiguously that the election would take place in summer 2007.

There was some controversy over which day of the week the election should have been held on, as some opposition parties insisted that a weekend polling day would have made it easier for those studying or working away from home to vote. Ireland's voter registration process presents difficulties for people who live at a second address for part of the week. Previous elections and referendums have been held on Thursdays, Fridays and (in one case) a Wednesday. For the 2007 election, polling day was a Thursday.

The Taoiseach denied that the election was called on Sunday 29 April 2007 to prevent the Mahon Tribunal recommencing investigations the following day concerning alleged payments to politicians (including Ahern). Because of the election campaign, the Mahon Tribunal suspended its public hearings on Monday 30 April 2007, and resumed them four days after the general election on 28 May 2007.

The closing time and date for nominations was 12:00 Irish Summer Time on Wednesday 9 May 2007.

Polls were open from 07:30 until 22:30 IST. The system of voting was proportional representation by means of the single transferable vote (PR-STV). The general election took place in 43 parliamentary constituencies throughout Ireland for 165 of the 166 Dáil Éireann seats (the Ceann Comhairle is automatically re-elected).

Campaign

As a result of falling opinion poll ratings for the outgoing government in the months approaching the start of the campaign, the election was one of the more closely fought in decades, with the outcome being very uncertain.

This election was fought as a contest for Taoiseach between the outgoing Fianna Fáil–Progressive Democrats coalition and the "Alliance for Change", a proposed Fine Gael–Labour Party coalition. Opinion polls did not show either option as being certain, and other possibilities include Fianna Fáil–led coalition with other parties, or Fine Gael and the Labour Party with the Green Party. Fine Gael and the Labour Party had an agreed transfer pact. The Green Party was non-aligned but made statements favouring a change from the outgoing Government. All parties, with the exception of the Green Party, claimed that they would not include Sinn Féin in a new Government.
