The Irish Reunification movement has existed in some form since Ireland was partitioned into two countries in 1921. Ireland is made up of Northern Ireland, a member of the United Kingdom, and the Republic of Ireland which is a sovereign state and member of the EU.
As part of the Good Friday Agreement and the Northern Ireland Act 1998 provides that the Secretary of State for Northern Ireland "shall exercise the power to hold a referendum if at any time it appears likely to him that a majority of those voting would express a wish that Northern Ireland should cease to be part of the United Kingdom and form part of a united Ireland".
Will Northern Ireland hold a reunification referendum before 2030?
This question will resolve as Yes if the Secretary of State for Northern Ireland holds a referendum on the question of reunification with Ireland before January 1, 2030, 12PM GMT.
