Polls on both sides favor it now.
Voters in both Northern Ireland and the Republic of Ireland see themselves united as one country in the next 10 years, according to polls conducted on both sides of the border.
South of the border, 62% of people favor Irish unity, though the majority view it as a long-term project rather than an immediate priority, according to a poll for the Irish Times/Ipsos MRBI. The most popular timeline for a referendum was “in the next 10 years.”
A separate poll by Lord Ashcroft in Northern Ireland showed a majority think there should be a border poll some time in the future. If a referendum were held in 10 years time, two thirds thought it would see a vote in favor of a united Ireland.
The U.K. has retained control of the six provinces of Northern Ireland since the southern part of the island won independence a century ago, but set out the terms on which reunification could take place in the Good Friday Agreement in 1998. Referendums would need to be held on both sides of the border. Only the U.K. can call a ballot in the north, and it is obliged to do so if it seems likely that voters would choose reunification.
