It’s non-binding because NO referendum can bind Parliament, because Parliament is sovereign.
But the discovery of a highly motivated voting bloc that makes up 54% of the vote - 57% in England - changes everything.
This is a golden opportunity for the Conservative party. If Boris Johnson becomes PM in the october conference, then he can declare a snap election and grab this 54% vote.
If the Conservatives drop the ball and select Teresa May for PM, then it all becomes more murky. But Farage + UKIP would still be there, keeping the issue front and centre, and waiting for the next election.
And in the meantime, secessionist movements in Netherlands, France etc will move forward.
This liberal idea that UKIP is now going to disappear is a delusion.
