evidence: Almost a fifth of voters in Northern Ireland, including nearly a third of voters from a Protestant background, say they would find a vote in favour of a united Ireland "almost impossible to accept", according to an Ipsos opinion poll. [...] In Northern Ireland, just under half (47 per cent) of all voters said they would "happily accept" a vote in favour of unity. A further 26 per cent said that they "would not be happy but could live it", but 18 per cent of all voters — which includes 32 per cent of voters from a Protestant background, and 14 per cent of voters from a non-Catholic and non-Protestant background — said they would find this result "almost impossible to accept". Acceptance of a pro-union result was much higher. Almost three-quarters of voters (73 per cent) in the North said they would "happily accept" this outcome, with 19 per cent reluctantly accepting it and just 2 per cent who said they would find it "almost impossible to accept".
