The UK’s vote to leave the EU will not only break the ties between the UK and the bloc, and probably between Scotland and England — it has the potential to destroy the eurozone. This is not the issue at the forefront of people’s minds right now. But it is potentially the biggest impact of all. I am convinced Brexit’s consequences will be neutral to moderately negative for the UK but devastating for the EU.

The main problem is not other countries wanting to hold EU referendums. The problem is more acute. The next referendum to be held in the EU takes place in Italy in October. It is not about the union but about Matteo Renzi’s constitutional reforms. The Italian prime minister is taking a gamble which is no less risky than David Cameron did.

He is asking the Italians to agree a number of reforms to streamline their political system. The proposals are sensible. But Italians view the referendum as an opportunity for a midterm anti-government vote. Mr Renzi promised he would resign if he loses. If he does, it will have been a monumental error of judgment on the scale of Mr Cameron’s. Opinion polls have been showing a small lead for Yes but they are likely to be as unreliable as those in the UK. My Italian friends are telling me Mr Renzi may well lose, in which case he would either resign immediately or call elections in early 2017.
