"MPs who vote to block no deal would "destroy" the government's Brexit negotiating position."
Since it is obvious the EU won't agree to a deal without the backstop, it's deceitful of Boris and his mates to claim that they can still do a deal without the backstop, and even worse to say that ruling out 'no deal' weakens our position. Our position would be much stronger if Boris were honest about the situation. For goodness sake, just stay in the customs union and single market.
