Much as I would have liked to respond factually and truthfully to each and every piece of misinformation spread by the Brexit campaign, it was important that I stayed out of the domestic political debate. It was David Cameron's task to win the UK referendum, not ours.

I am, however, deeply saddened by this [Brexit] vote by the British electorate. But I respect their decision. What is crucial now is that we focus very precisely on what Europe can do for people: stimulate investment, create jobs and together ensure the safety and security of our citizens.

As a human being I am personally saddened, as I have a great deal of respect for the large number of British colleagues I have worked with over the years. That is why I personally invested countless hours, days and nights, in negotiating a fair deal for the United Kingdom.

I have a plan. It entails leading to a fair deal and relationship with the British. We will be reasonable, but we will also negotiate firmly and without gullibility. I believe we must come to an agreement for the people of Britain and the people on the Continent, but not under exclusively British terms.

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

My friendship with Martin [Schulz], by contrast, is completely different in that it goes far beyond politics.

Trump knows that he is encountering a complete lack of understanding in Europe, but it's apparent that he's not very impressed by it. My experience, however, has been that American presidents take a greater interest in Europe over the course of their term.
