What on earth is up with British unionism? Although not especially reflective at the best of times, this ideology has recently been thrust into explicitness in disturbing ways. It’s often said that Brexit is in part driven by an upsurge of English nationalism, but I don’t buy that – if only because there’s no such extant thing (yet) as English nationalism. It is, rather, the laying bare of the nationalism that England has instead of its own, which is the nationalism of the UK – aka unionism. And while it isn’t necessarily worked out in any compellingly abstracted form, it is still not properly understood.

This nationalism is profoundly Anglocentric, to be sure, but its commitment to the United Kingdom is just as profound – when Theresa May insists that she won’t countenance dividing the kingdom in order to ensure an open border in Ireland she’s not just parroting the DUP’s lines. But the UK it has in its heart is one in which English dominance is taken as read, and which is hostile to any serious checks on the sovereign power located at Westminster and Whitehall. Devolution is fine as long as it can be overruled when necessary, and as long as it’s the centre that gets to decide when it is necessary. But everything touching on the constitution that has happened with the approach to Brexit makes clear that the Westminster government’s freedom to propose and dispose must be untrammelled and unchecked.
