This whole debate idea is meaningless political theatre. Two brexiteers arguing about current terrible deal that's worse than remaining versus unicorn slightly less terrible deal that's worse than remaining and has no time to be negotiated. And as PJV3 says, without a public vote at the end what's the point? It just seems like a bizarre hail mary play by the PM, to try and get the public inside in the belief that will pressure MPs to go along with her shitty deal.
