Steve,
Keith, if you really think that, even now, the vast majority of the voting public could explain to you what the single market and the customs union are, you're in cloud cuckoo land.

The Far Left has always been contemptuous about the people you called "plebs" because they refuse to elect you.
I do not share your contempt for the people of this country.

A summary of Labour's state of play from the Observer, backed up with the results of a survey:

It was a survey, of "potential Labour voters" (?) conducted for the Observer, by something called "Opinium."

Not very impressive, and according to you they do not know what the single market and Customs Union are anyway!
