Well i still want to know what this good deal looks like and how they are going to get it
A good deal in my mind involves a sensible exit payment (say £30bn), agreement on rights for UK citizens in the eu and vice versa, say an exchange of nationalities, and binding basics of a trade deal.
A bad deal involves a large payment to the eu (say £70bn+), unilateral granting of rights to eu citizens in the UK and nothing on trade.
No deal means no real payment to the eu, citizenship entirely in our control and no trade deal.
In that context, no deal is definitely better than a bad one.
