Article 50 governs the exit from the European Union and here there can also be no renegotiation.

I am for it - not to make a threat, but to make clear that decisions that have been made are applicable law, even if you have voted against it. At issue here is European solidarity, which cannot be a one-way street. The traffic has to move in both directions.

In 1913 many believed that there would never again be a war in Europe. The great powers of the continent were so closely intertwined economically that the view was widespread that they could no longer afford to have military confrontations.

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

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

But it is the best thing that we have for bringing the countries of Europe around the same table and for forging compromises so that people here can live in peace, freedom and prosperity. In a world which is growing closer together all the time, we can only survive and influence the rules if we join forces. We will miss the presence of the United Kingdom at this table.

We must go back to teach Europeans to love Europe.
