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

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.

I am chilled by the realization of how similar circumstances in Europe in 2013 are to those of 100 years ago.

Yesterday's shining heroes of Brexit have become the sorrowful heroes of today.

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

Since it took up office, the Commission which I lead has pursued a clear policy: we need less interference from Brussels when it comes to the things that Member States can deal with better on their own. That is why we no longer regulate oil cans or showerheads, but concentrate instead on what we can do better together rather than alone - such as tackling the refugee crisis or securing our external borders. Only in that way can we make people feel that Europe makes a tangible difference.

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.
