Unionism in Northern Ireland is facing a highly uncertain future. Its divided party politics make the headlines. But beyond that, post-Brexit border rules and talk of a possible vote on Irish reunification is causing much anxiety. Even more profoundly, changes in the province’s population and attitudes among different generations are weakening traditional loyalties. Pessimists fear all this could be seriously destabilising. Others argue that a new kind of unionism, focused on the practical benefits of links to Britain, can revive the cause. Chris Bowlby listens in to a debate with major implications for the UK as a whole.
