On Tuesday the Supreme Court gave the responsibility for Brexit back to Parliament. The consequences of that ruling are making themselves felt, the most important being the bill on triggering Article 50 that the Government published yesterday. Yet the bill is not the very first fruit of the court’s constitutionally unanswerable decision. Until she stood up at Prime Minister’s questions on Wednesday, Theresa May was also insisting there would be no white paper on Brexit goals either. Yet, faced with a newly empowered House of Commons, Mrs May has been forced into a U-turn on that refusal too. Within 48 hours, the Government has been compelled to take Parliament more seriously. Mrs May changed her mind because of parliamentary numbers. This Government has a working majority of only sixteen: if the main opposition parties can find common cause with pro-remain Conservative MPs, that majority is threatened. Note: Scotland, Wales, and Northern Ireland now have no formal power of veto over withdrawal.
