Sligo–Leitrim Independent Socialist Organisation (SLISO) was a minor political party led by Sligo County Councillor Declan Bree. It was set up in 1974 and contested local elections to Sligo County Council and Dáil Éireann elections for the Sligo–Leitrim constituency. The group stood other candidates but Bree was the only candidate ever elected for the group.{{cite web| url = http://electionsireland.org/party.cfm?election=1991L&party=ISP| title = ElectionsIreland.org: Party Candidates| access-date = 2011-08-11| archive-date = 2011-10-16| archive-url = https://web.archive.org/web/20111016161211/http://www.electionsireland.org/party.cfm?election=1991L&party=ISP| url-status = dead}}{{Cite web|url=https://irishelectionliterature.wordpress.com/category/sligoleitrim-independent-socialist-organisation/|title=Sligo/Leitrim Independent Socialist Organisation|access-date=11 August 2011|archive-date=2011-07-14|archive-url=https://web.archive.org/web/20110714150044/http://irishelectionliterature.wordpress.com/category/sligoleitrim-independent-socialist-organisation/|url-status=live}} In 1991 the group merged with the Labour Party and Bree was elected as a Labour Party TD at the 1992 general election.
