The Ulster Unionists have basically given up on doing anything as a protest against the Tories back in Westminster, who have basically screwed them over to get their majority. Meanwhile, Sinn Fein have stopped their protest and started working again, and there does seem to be an appetite for a referendum on reunification. It’ll cause some people to lose their minds over it, but Eire has been the good guy on that side of the Irish Sea, and Westminster have all but abandoned them with the Northern Ireland Protocol. Whether Westminster allows such a referendum is another thing, if it does happen, it’ll be after Scotland get theirs, and hopefully along with Wales, they’ll get their say in the matter.
