The prophets of doom need a cause. The flavour this year is Brexit failing and the downfall of civilisation as we know it. Every hack has an informed source to prove the point; conspiracies, rebellions and incompetence abound in every corner of the Tory camp. Allegedly.
So may I respectfully aver that the Eurolands have no interest in a dead Brexit, whatever their unelected prats may say. In the next two years the wobbly wilderness aka the EU will be struggling to avoid further flounces, bankruptcies and distractions; never mind scoring a famous own-goal by upsetting its almost-former member, their trusted trading partner.
So come on Ms May, do it on Tuesday and stick it to those self-satisfied Europrats.
