How an we negotiate terms with people who have no wish to negotiate?
The rules of the EU are set in stone and it was always going to be the case that we leave unilaterally or sell out the people who voted to leave and won the referendum.
Not only do the EU not want to negotiate in a meaningful way beneficial to both parties, but they simply cannot allow us to leave with a reasonable deal.
The UK will never countenance any return to "Free movement" and that policy is integral to the survival of the EU.

We will have no option after the posturing, other to walk away into a better and more democratic future.
