Quite right. He and Aaron Banks talked up the ‘Norway Option’. But their campaign was more about immigration.
It was Johnson (even after the referendum) and Daniel Hannan that said we would continue to be in the single market (Hannan) and have ‘access’ to it (Johnson). I suppose Johnson can wriggle out of it by saying ‘access’ doesn’t mean ‘in’, but every country in the world has ‘access’ to the Single Market, just on much worse terms than being in it.
Given the way things are going the Norway Option sounds fine to me.
Yes, Johnson said we would have access to the Single Market. We do under WTO rules. I cannot find any reference to him saying we could retain membership of the Single Market.
