The 4 Irish constituencies in the European elections. 3 MPs were elected in each constituency.
The European elections in the Republic of Ireland took place on Friday 5th June 2009. Local elections were also held in Ireland in parallel. There were also two by-elections to the Irish Parliament in the constituencies of Dublin South and Dublin Central , as their constituency representatives had died.
As a result, 4 parties and an independent candidate shared the 12 Irish seats: Fine Gael 4 seats (29.1% share of the vote), Fianna Fáil 3 seats (24.1% share of the vote), Labor Party 3 seats (13.9% share of the vote) and Socialist Party 1 seat (2.7% share of the vote). The Labor Party under Eamon Gilmore , which gained two seats compared to the 2004 European elections , was the main winner . The biggest loser was Sinn Féin under Gerry Adams , who received nothing despite the 11.2% share of the total vote due to the current electoral system. The voter turnout of 57.5% was about the same as in the last European elections (59.0% at the time).
The election took place according to the principle of transferable individual voting in four large constituencies ( North-West , South , East and Dublin ), in each of which 3 members were elected. Compared to the 2004 European elections, the number of Irish MEPs to be elected was reduced from 13 to 12. In order to do justice to this change, the number of MPs to be elected in the Dublin constituency was reduced from 4 to 3 and the counties of Longford and Westmeath were annexed from the constituency of East to the constituency of North-West .
