I note that many British MEPs belonging to the UK Independence Party (UKIP) have used all their time in Parliament to work against the institution of which they are members. I would not presume to advise them on what they should or should not do. However, since the UK could not leave the EU fast enough as far as they were concerned, I can imagine that they will not stay any longer than they have to.

With hindsight, it is always easy to blame everyone else.

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.

My father was a steel worker and Martin's [Schulz] grandfather was a miner in Saarland. In these occupations, there is a particular awareness of solidarity. That creates links that aren't present in other relationships.

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

Here in Brussels, we did everything to accommodate David Cameron's concerns. My collaborators and I personally spent countless days and nights negotiating an agreement that was fair toward the United Kingdom and toward the other 27 Member States. I was then very surprised to see that this settlement played no role whatsoever in the campaign in the United Kingdom. At the same time it is hardly surprising.

From the very beginning Europe has been not only a success story but also a story of success achieved by learning.
