Speaking on arrival at a summit of EU foreign ministers in Brussels, Foreign Secretary Boris Johnson said it was important not to pre-judge the American President-elect Donald Trump.

Mr Johnson said: "It’s only a few days since the election has taken place. I think we all need to wait and see what they come up with but I think we should regard it as a moment of opportunity."

"Donald Trump, as I’ve said before, is a deal maker and I think that could be a good thing for Britain."
