EU countries have given the go-ahead for more "intensified" Brexit talks to take place, the BBC has been told.
This comes after a meeting between Brexit Secretary Steve Barclay and EU chief negotiator Michel Barnier, described by both sides as "constructive".

A summit next week is seen as the last chance to agree a deal before the Brexit deadline.
UK Prime Minister Boris Johnson put forward revised proposals for a deal last week, designed to avoid a hard border on the island of Ireland after Brexit.
BBC Brussels correspondent Adam Fleming said it was "not clear" how the forthcoming talks were going to be described, but "some form of intensified negotiations" would take place.
He added that, although there would be a "measure of confidentiality", EU states would still be briefed on any developments.
