Brexit process will start in early 2017, Boris Johnson says

Boris Johnson, the current British foreign minister, said that since early 2017, it will start the divorce process by the European Union and then Britain will most likely invoke Article 50. In this way the former mayor of London spoke in New York where United Nations Security Council held meeting on Syria perpetuating stalemate.
He told the BBC: "The government is working towards an Article 50 letter which as you know will be produced, probably, in the early part of next year.
"That's still subject for discussion but what is clear I think to our friends and partners in the EU is two broad principles: we are not leaving Europe; and he added that "Although we are leaving the EU treaties, we do want to have the closest possible trading relationship and it's very much in their interests to achieve that… it's very much in their interests to do a great free trade deal with us, and I think that will happen."
As The Guardian reported, Johnson gave an idea of the "new life" for UK: “We are going to benefit from the fantastic opportunities for greater free trade with our friends in the EU,” he said. “It’s overwhelmingly in their interests. Not only do we buy more German cars than anybody else, we drink more Italian wine than any other country in Europe – 300m litres of prosecco every year. They’re not going to put that at risk.”
