Dáil constituency (1997–present)
Mayo is a parliamentary constituency represented in Dáil Éireann, the lower house of the Oireachtas (the Irish parliament). The constituency elects five deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV). It includes the entirety of County Mayo.
History.
At the 2002 general election Fine Gael suffered its worst electoral performance ever, losing 23 seats nationally, a figure larger than expected and with its overall vote down 5%. Enda Kenny came close to losing his seat and even went so far as to prepare a concession speech. In the end, he won the third seat in the five-seat constituency.
At the 2011 general election, this was the constituency of Fine Gael leader Enda Kenny, who became Taoiseach after the election. Fine Gael won four out of five seats in Mayo at that election. This was the first time any party won four seats in any five-seat Dáíl constituency; the last time any party had won four seats in a Dáil constituency was in the era of six- and seven-seat constituencies.
Boundaries.
Mayo is the largest Dáil constituency in Ireland by area. Its largest towns are Castlebar, Ballina, Westport, Claremorris and Ballinrobe. It is defined by the Electoral (Amendment) Act 2023 as:
"The county of Mayo."
The constituency was used for the first time at the 1997 general election and replaced the former constituencies of Mayo East and Mayo West.
