A 2019 poll by Ipsos Mori and King's College London asked people in Great Britain (England, Scotland, and Wales): "If there were to be a referendum in Northern Ireland on its future, would you personally prefer Northern Ireland to choose to stay in the UK or leave the UK and join the Republic of Ireland?" The responses revealed that 36% wanted Northern Ireland to stay in the UK, 19% wanted it to join the Republic, 36% had no preference, and 9% were undecided. It further revealed that support for Northern Ireland remaining in the UK was highest among those who intended to vote Conservative (49%) compared to 35% for Labour voters and 31% for Liberal Democrat voters.
A 2023 state of the union poll asking if Ireland should unite showed that respondents from Northern Ireland, Scotland, Wales and England all had net positive views on the unification. On a scale from −10 to definitely remain in the UK to +10 to definitely unite Ireland; the people of Scotland had a net score of +1.9, England at +0.9, Wales at +0.6, and those in Northern Ireland at +0.6 also.
