How Northern Ireland votes
Northern Ireland elects the Northern Ireland Assembly (90 members) by the Single Transferable Vote, alongside its Westminster seats.
Westminster elections use First Past the Post in all four nations. Polls shown elsewhere on this site are UK-wide unless a named pollster published a Northern Ireland-only poll.
