The abortion referendum may have done for the DUP.

Arlene Foster’s outfit presents itself as the hardest-line “pro-life” party around but depends on a constituency as pro-choice as any other on the island. This contradiction has long been lurking at the edge of Northern politics. It’s been brought out into the open and neon-lit by the giddy triumph of Repeal.

Foster, Sammy Wilson, Nelson McCausland etc. queued up for the cameras to insist that the scenes of joy at Dublin Castle had nothing to do with the North. They were wrong about that, and are wrong, too, in imagining that they speak for a Northern majority – or even a majority of Northern Protestants – or even a majority of DUP voters – when it comes to women’s rights.
