Remaining part of the UK still has a ten point lead. Support for Irish unity is higher than in most recent polls, but the drop in support for the union is not statistically significant. This is at most an argument that a border poll in two decades time might be close.
that's ignoring demographic change (UI leads among voters under 45 and pensioners are the most unionist) and that the poll has 52% saying they aspire to a UI at some point in the future (given a point over 10 years in the future) with only 44% saying they would never support leaving the UK.
