The SLP regarded itself as highly progressive. It allowed for the right of factions to organise within the Party. However, the various Trotskyist groups, within, became so pre-occupied with this provision that they effectively abandoned the uniting principal, the raison detre of the Party.
In the absence of Party unity, the Executive Committee took the decision to dissolve the SLP. The SLP won much admiration for its principled and progressive stance within the Irish Left.
Only in recent years have the various factions, parties and movements of the Left in Ireland begun to learn from the experience of the SLP and realise the original goals and visions of Matt Merrigan and Noel Browne.
