This has nothing to do with May needing "to impose her will." Last time I heard she was the prime minister of a territory that fully includes Northern Ireland. For the last sixteen months there has been no devolved administration in the Six Counties. Yet that part of our nation still has to be administered. Westminster parliament has every right to legislate to change the law in NI. I'd go a lot further than that and say that May has a DUTY to the women of NI to give them the same human rights as women elsewhere in the EU. She can't escape this. Ireland has utterly turned the tide, and she has to act despite the DUP, and if that leads to an election, then that's how it should be. Whatever happens, the DUP shitbags are doomed.
