Solidarity (Irish: Neart le Chéile), formerly known as the Anti-Austerity Alliance[5] (AAA), is a socialist political party in Ireland, launched in 2014.

[11] Paul Murphy was elected to Dáil Éireann for Dublin South-West under the Anti-Austerity Alliance banner at a by-election in October 2014.

According to the Irish Examiner, Barry had been "a leading figure in the Cork and national campaigns" against household and water charges.

This name change was made to reflect the "many movements emerging on workplace, economic and social issues" and that while "the AAA has played a key role in campaigns like the water charges and housing", that the organisation under the name of Solidarity "will continue to do so, but the name will now better reflect our campaigning work on Repeal, LGBTQ issues and equality generally.

"[17] Cork City Councillor Lil O'Donnell left the party at the time of the rebranding as Solidarity.

[22] The Phoenix has opined that this position is a "bizarre fusion of Trotskyism and British Unionism" that "articulates a unionist outlook dressed in socialist rhetoric".
