Northern Ireland is part of the UK. It is ruled from London, so if the UK government says they will have legal abortion, then they will have legal abortion.The Republic of Ireland has abortion legal during the first 12 weeks. After that for the life&health of the mother.
Well, it wouldn’t if SF and the DUP hadn’t crashed the NI government and forced London to rule them directly. Ironically, the British government wouldn’t be fojng this if it wasnt being supported by the Irish Republicans.
