The Socialist Party has confirmed it has withdrawn from the United Left Alliance, the group it formed with the People Before Profit Alliance and some left wing independents.

The ULA, which won five seats at the General Election, is now reduced to three TDs; Richard Boyd Barrett and Joan Collins of PBP, and Clare Daly, the former Socialist Party TD who is now an independent.

In a statement, the Socialist Party said it was leaving "with regret" but accused some members, "including TDs", of moving away from a principled left position and collaborative spirit.

The statement said the ULA was already weakened because ordinary working class people had not joined in any significant numbers, and the Workers and Unemployed Action Group of Tipperary had already left, along with its TD, Seamus Healy.
