I think you're not understanding what he meant by context, the context is that just before then he'd said it was a mistake to give the UK electorate a leave/stay questions, he meant he'd simply give France a stay/stay question, i.e.:
Would you:
1. like to stay in the EU as is or
2. like to stay in the EU with minor tweaks?
It's too complicated for the peasants to understand apparently.
But if given a leave/stay question, he thought France would vote leave like the UK.
He then went on to have a rant against all the unwashed who'd lost out because of globalization gobbling their livelihoods and how they should damn well be pleased to be screwed, if you're not a university educated elite it's your own fault for sucking, politicians obviously aren't meant to represent you or your views.
