BBC News Published image copyrightGetty Images A majority of people on both sides of the Irish border believes Northern Ireland will have left the UK within 25 years, a poll suggests. Most respondents said they thought NI would still be part of the UK in 10 years time, but not in 25 years. In NI, 49% of people said if there was a border poll today they would vote to remain in the UK, with 43% backing a united Ireland and 8% undecided. The poll was commissioned by BBC NI's Spotlight programme. In the Republic of Ireland, where a vote would have to be held in parallel with any border poll in Northern Ireland, 51% said they would vote for a United Ireland, 27% would vote for Northern Ireland to stay in the UK and 22% were not sure.
