The Belfast Agreement – including the linked changes to the Irish Constitution and the UK Northern Ireland Act, 1998 – is a central point of reference in the developing discussion of a united Ireland.
It provides that the people of Ireland have a right to self-determination, but only on the basis of the concurrent consent of majorities both North and South. A referendum must be held in Northern Ireland if the Secretary of State believes that a majority in favour of unity is likely.
