Next time UK considers leaving Europe it wont be with so many caught up in a 50/50 decision and they'll be no referendum imo, it just be on the more obvious conditions at that time.
I think EU in effect leaves us tbh it will be without politics or speculation. Possibly it might be in future more of a party vote, I think that was Cameron's decision now to stop it being part of the election vote by doing this separately. That depends on EU problems passing in time not increasing
EU has some of the lowest growth in the world, the biggest reason to leave is to be more invested globally not just regionally but that idea was very unclear when the largest companies favour EU regulatory enforcement.
The fastest growth comes from the smallest business who struggle to deal with EU constraints and costs, even such as ocuk once was so I think that message was easily lost unfortunately.
