Britain and the European union are at an impasse over changes to the parts of the Brexit deal governing trade with Northern Ireland, Britain's Europe minister James Cleverly told a parliamentary committee on Thursday.
"The truth is that we have come to something of an impasse, and I don't think that's through a lack of goodwill, and I think it's more through what we regard in the UK as an overly limited (EU) negotiating mandate," he said.
