It could actually be true that the UK isn’t at the table SINCE article 50 was invoked. In which case, he voted for the situation.
Its obviously bollocks that only France and Germany negotiate trade deals for the EU. You have to wonder about the mentality of someone who can hear that somewhere and pass it on as a fact. Unfortunately, there are likely many millions more like him gagging to vote Brexit party. And they wont change their mind in a 2nd referendum anyway because they’re not rational or open to arguments.
Better to revoke now and ensure it can’t ever be re-invoked without a parliamentary majority.
