First-time Labour TD Ciarán Ahern has apologised to his Labour Party colleagues after his tweet defending the People Before Profit Solidarity TD Paul Murphy caused “a lot of hurt” across the party.

His post on X followed comments by Fine Gael candidate Heather Humphreys relating to the treatment of former Labour leader Joan Burton at an anti-water charges protest in 2014.
