Militant Left (Ireland)

Militant Left is a Trotskyist political party active in both the Republic of Ireland and Northern Ireland. After a split, in 2019, in the Committee for a Workers' International (1974), the group was founded by former members of the Socialist Party who wished to affiliate to the 'refounded' Committee for a Workers' International (2019). Initially known as CWI Ireland, it renamed itself Militant Left in 2020.

The group has no public representatives. Donal O'Cofaigh, initially elected as a Cross-Community Labour Alternative candidate, served as a councillor on Fermanagh and Omagh District Council for one term, from 2019 until 2023.

As of February 2021, Militant Left was not included on the register of political parties in Northern Ireland or the Republic of Ireland.
