I put my money on Brexit. The EU Financial Stability Commissioner, Jonathan Hill from Britain, still owes me a pound.

Between now and then, after 43 years of European marriage, the whole body of legislation will therefore have to be disentangled. That entails a whole range of specific and very complex questions: what will be the future legal status of the millions of EU citizens in the UK and the millions of Britons on the continent?

I have changed the focus of the work of my Commission so that we no longer concern ourselves with trivial details and concentrate on the key issues instead. By doing that, we met a large number of the legitimate demands made by the British people. The Commission really did do everything it could to create the conditions for a positive campaign.

Those who are saying that Mario Draghi is in the camp of those trying to push Greece outside the Euroarea, are wrong.

Germany will continue to play a central - perhaps even a more important - role in the European Union. I think that we will all miss the pragmatic approach of the British, however, particularly in those long nights of negotiation.

The position of EU commissioner for economic and monetary affairs could be combined with the office of Euro Group chairman. That job would be a great challenge for anyone who assumed it. On the one hand, he would have to make proposals. On the other hand, he would have to negotiate compromises with his European counterparts.

Now it is firstly a matter of a clean divorce, because citizens and companies need legal certainty. Can there be a new partnership with the United Kingdom one day? All 27 Member States would have to agree to that. And the United Kingdom would first have to reflect on what it wants itself.
