People Before Profit has called on Sinn Féin, the Social Democrats and other opposition left parties to form an alliance that would shun Fine Gael and Fianna Fáil following the next election.
However, the Labour Party has not been included in the discussions to form an election pact, the Irish Mirror understands.
People Before Profit has said that the next Government should not consist of either Fianna Fáil or Fine Gael and that the left should unite ahead of the election, which is scheduled to take place in or before 2025.
