Leitrim–Sligo (Dáil constituency)

Leitrim–Sligo was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1923 to 1937. The constituency elected 7 deputies (Teachtaí Dála, commonly known as TDs) to the Dáil, on the system of proportional representation by means of the single transferable vote (PR-STV).

History and boundaries
The constituency was defined in the Electoral Act 1923 as:
 * "The administrative counties of Leitrim and Sligo."

This was the first time that the Dáil had not used constituencies defined under British law. Leitrim–Sligo replaced the old Leitrim–Roscommon North and Sligo–Mayo East constituencies, which had been created under the Government of Ireland Act 1920. The constituency was first used at the 1923 general election.

Under the Electoral (Revision of Constituencies) Act 1935, the Leitrim–Sligo constituency was abolished, and replaced for the 1937 general election by two separate 3 seat constituencies: Sligo and Leitrim. The territory was reunited as Sligo–Leitrim under the Electoral (Amendment) Act 1947, in operation from the 1948 general election. The Sligo–Leitrim constituency was abolished at the 2007 general election, and replaced by two new constituencies: Roscommon–South Leitrim and Sligo–North Leitrim.

1932 general election
The vote was delayed two weeks in Leitrim–Sligo due to the assassination of Patrick Reynolds TD two days before the election was to take place. His widow Mary took his place on the ballot and was elected.

1929 by-election
Following the death of Fianna Fáil TD Samuel Holt on 18 April 1929, a by-election was held on 7 June 1929.

1925 by-election
Following the resignations of Cumann na nGaedheal TDs Thomas Carter and Alexander McCabe on 30 October 1924, a by-election for both seats was held on 11 March 1925.
