evidence: In 2023, 30 per cent in the North said they would vote in favour of unification (compared to 27 per cent in 2022) and 51 per cent to stay in the UK (compared to 50 per cent last year), with the remainder saying they either "don’t know" or would not vote. Three-fifths of Northern Catholics say they would vote for Irish unity, while four-fifths of Protestants say they would vote to stay in the UK. There is a much larger proportion of pro-UK Catholics (one in five) than pro-unification Protestants (four per cent). [...] In the South, 64 per cent said they would vote for unification compared to 16 per cent who said they would vote for Northern Ireland to stay in the UK, while 13 per cent said they did not know how they would vote and 7 per cent said they would not vote.
