Boris Johnson has claimed no prime minister would be right to accept the trade terms being offered by the EU, as he prepares to fly to Brussels for last-ditch talks.
The PM vowed not to cave in to "punishing" EU demands ahead of a crunch showdown this evening with Brussels boss Ursula Von Der Leyen.
He stressed this lunchtime that no PM would sign up to rules where we didn't have control over our fishing waters - or would have to mirror all future EU rules.
The PM will tonight have a crunch dinner with EU boss Ursula Von Der Leyen as he tries to salvage the chances of getting a deal done in time for New Year.
And before he dashed off to Brussles he said "a good deal is still there to be done" but lashed out at their demands.
At PMQs this afternoon he blasted: "Our friends in the EU are currently insisting that if they pass a new law in the future with which we in this country do not comply or don't follow suit, then they want the automatic right to punish us and to retaliate.
"Secondly, they are saying that the UK should be the only country in the world not to have sovereign control over its fishing waters.
"I don't believe that those are terms that any prime minister of this country should accept."
Britain will prosper "mightily" with or without a deal, he said.
He vowed that Britain would become a "magnet for overseas investment".
The PM said: "This country will be ready for whether we have a Canadian or an Australian solution, and there will be jobs created in this country, throughout the whole of the UK, not just in spite of Brexit but because of Brexit."
But Boris' tough-talking comes hours after Mr Gove said earlier that Britain is prepared to make a "very generous" Brexit compromise overfishing in order to seal a deal.
Fish is one of the biggest sticking points in the talks and has long been an argument for Britain to leave the EU and get back control of our own waters.
