Brexit: Barclay and Coveney voice opposing views on backstop The UK's Brexit Secretary Stephen Barclay and Ireland's Deputy Prime Minister Simon Coveney, both invited in Paris by MEDEF, the largest employer federation in France, voice opposing views on the backstop, a provision guaranteeing that border checks will not return between Ireland, an EU member, and Northern Ireland, which is part of the United Kingdom. British Prime Minister Boris Johnson said that the European Union needed to drop its insistence to avoid a "no deal" Brexit during the G7 summit in Biarritz. IMAGES AND SOUNDBITES
