Yes, it's a question we've asked before. This time, no one seems to know. Everyone on our side is terrified that Boris will have given away too much, whilst the Remainers are praying that Boris won't concede enough to allow the EU to change May's Surrender Treaty, thus giving them scope for a second cancelling Referendum (which they will lose if it allows a single Leave option).
No one can get angry until the deal is published. We don't know what the deal proposes. Journalists know no more than I do - they stood outside the Berlaymont last night counting the lit windows and reporting the times at which the lights went out (most by 2.30, it seems).
So our barrels are charged with powder and shot, slow match is burning, and we are waiting. Ready to douse the match and fetch the shot-screw or otherwise.
