My own view... is that the United Kingdom will have to sort of architect a sort of rapprochement, or re-entry into the European Union in one shape or form
I'm not sure if he's claiming that Brexit is the reason for EU troubles, but I dunno because I haven't listened to the full interview (which is here, but I think you need to be in the UK to listen to it)
Maybe he's referring to the political troubles in Germany and France - the governments of both countries have collapsed recently
