Tory nutters seek to torpedo a deal with the EU.
Currently UK policy appears to want to carry on as a member of the single market and the customs union during the planned two-year transition.
Iain Smith and some extremist anti-Europeans aim to prevent an agreement by demanding impossible and contradictory conditions.
They seem to want full access to the single market post-Brexit while refusing to conform to EU rules.
I suppose they're trying to get an early election by making Theresa's shaky coalition of chaos collapse.
Bring it on.
