Sinn Fein members have voted in favour of liberalising abortion law in a change to the party’s policy.
Delegates at an annual party conference in Belfast said the procedure should be provided through a GP-led service for a “limited gestational period”.
They also decided abortion should be available where a woman’s life, health or mental health is at risk and in cases of fatal foetal abnormality, where an infant cannot survive.
It comes after last month’s referendum decision to overturn a constitutional provision in Ireland which outlawed terminations in most cases.
Vice President Michelle O’Neill said: “Sinn Fein refuses to hide.
“It will address this issue with compassion and will show the leadership that is required.”
