Jeremy Corbyn it had to try. If the British opposition leader had – with restrained words – sent a very battered Prime Minister without a motion of no confidence, he would have abandoned serious policy. On the other hand, if British parliamentary rules provided for a constructive vote of no confidence, Corbyn would have had to prove that he could do more than hold fiery speeches and demonstrate against allegedly evil in the world. Then he would have had to negotiate with other parties about how a government led by him could find a way out of the Brexit mess. That would have meant compromise. And that’s exactly where the left-wing hot spur hampers.
This is bad news for the UK. A change of government would actually be logical in the current situation. The incumbent Prime Minister has proved incapable of mastering an admittedly difficult situation. Large parts of their own party have opposed them. But you have no organized opposition to takeover. So Theresa May is allowed to continue.
Their victory in the vote of confidence was to be expected. Nobody has a serious interest in a new election except Labor. And not even the toughest Brexit ideologues are so blinded that they wanted to give Jeremy Corbyn a realistic power option.
