BRUSSELS (Reuters) - British Prime Minister Theresa May said on Wednesday she believed a Brexit deal was achievable if both sides worked “intensively” in the coming days and weeks.

“What we’ve seen is that we’ve solved most of the issues in the withdrawal agreement. There is still the question of the Northern Irish backstop ... by working intensively and closely, we can achieve that deal,” she told reporters on arrival at an EU summit.

“Now is the time to make it happen.”
