EU council president Donald Tusk, speaking at a press conference following a meeting with Ukrainian President Petro Poroshenko, had a message for the UK:

“Some of my British friends have even asked me if Brexit can be reversed and whether I could imagine an outcome where the UK stays part of the EU.

I told them that in fact, the European Union was built on dreams that seemed impossible to achieve. So who knows? You may say that I’m a dreamer but I’m not the only one.”
