Amnesty International has threatened legal action if Northern Ireland becomes the only part of the UK not to ratify legal marriage for same-sex couples, reports the BBC.
A debate on whether to legalise same-sex marriage took place at the Northern Ireland Assembly yesterday, amid protests from both pro- and anti-gay marriage groups in the province.
The motion to legalise same-sex marriage was proposed by Sinn Fein. The Democratic Unionist Party (DUP) has indicated it may use a Petition of Concern to veto any proposed legislation. A similar motion was proposed and vetoed last October.
