Yes PP, but the promises/demands you refer to are all propaganda fantasy. Which is why it's denied. Presently cards are being played close to the chest to avoid giving an advantage to the other side of the negotiating table, in advance of getting there. Folk will be clear on what they expect the basics of the agreement to be, they just won't tip their hand in advance, just in case. The main issue is, will the reason to leave at all (sovereignty/control) be a sacrosanct demand or will it be sacrificed by weak negotiators ? Let's hope the folk who made agreements on tax with the multinationals are not invited to the Brexit negotions.
