Re: Just so much wind
The ERG are about 30 people. And Johnson isn't one of them. He actually voted for May's deal, as the least worst option at the time. Then despite it being supposedly "impossible" went off and negotiated a new one (minus the worst bits) - and has now said (and written into that agreement) that he wants a free trade agreement with the EU.
Apart from his views on the EU, I think he's much more of a Cameroon than any of them. Whereas the ERG are more Thatcherite-than-thou and certainly more Thatcherite than Thatcher ever was.
