Given all of this, Remain needs to explain why we wouldn’t be better off trying to diversify our economy towards more resilient parts of the world. The share of our exports that goes to the EU has already collapsed from 55 per cent in 1999 to 44 per cent last year – but shouldn’t we be trying to reduce this further and faster?

If the eurozone succeeds in harmonising its fiscal policies and becoming more like a single entity, it may succeed in overriding British interests more effectively, which could be another reason for us to leave.

The EU was always intended by its founders to be a process – a mechanism by which formerly independent European countries gradually bind themselves together into an ever-closer union. Crises were seen as useful flashpoints that would trigger a further push to integration, and its central institutions were deliberately designed to seek and accrue power.
