Brexit: Meeting with opposition Labour Party constructive, says May's deputy

British Prime Minister Theresa May's de facto deputy said there had been difficult moments in talks with the opposition Labour Party about how to break the Brexit impasse in the country's parliament but they had also been constructive.

"The mood inside the meetings has been constructive, it has been difficult at times, I won't deny that because there are differences between the two political parties," David Lidington, minister for the Cabinet Office, told reporters.

Earlier on Wednesday, a spokesman for Labour said the party would seek to clarify how far the government was willing to give ground in the talks.
