One year on the political weather has changed and suddenly a once unthinkable question can be asked: might Brexit be stopped?
The obvious shift is in the power of a government whose animating mission was meant to be British departure from the European Union.
Put simply – Theresa May sought a mandate for hard Brexit and didn’t get it.
That leaves the forces of leave weakened and remain emboldened.
The deeper if less tangible shift is that the case for leave is collapsing before our eyes.
Its central winning claim – that exit would bring £350m a week for the NHS – lives on now only as a punchline and case study in Trumpian dishonesty.
It will endure as a short sharp argument for why Boris Johnson must never be allowed to become prime minister and may well stand between him and his party’s leadership.
But most of all it encapsulates the notion that leave won last year on a false prospectus.
