I would describe that [friendship with Greek Prime Minister Alexis Tsipras] as a utilitarian friendship. At the time, his country was facing the prospect of leaving the euro zone and many Greeks felt abandoned by Europe. In such a situation, it seemed appropriate to me to present myself as a friend to Greece. It had to do with the country's dignity.

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

The will of the British people must now be put into effect as quickly as possible. Under Article 50 of the EU Treaty the UK must leave the European Union within two years at the latest.

The good thing about the European Union is that the joint project ultimately benefits all Member States and not just a few.

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

I am for secret, dark debates.

I don't think in national categories. For me it [policy] is about concepts and substance.
