It was never alive.
Its not even deliverable in Mays own Parliament and clearly undeliverable in EU?
May has been repeatedly advised by EU that theycould not “cherrypick”. It could not be in the single market for goods (as the Chequers plan proposes) but outside of it for services.
Before, UK was in and had many opt-outs; now they want to be out with many opt-ins.
There is no cost-free option for the UK - Brexit cannot be delivered in the terms that it was promised.
UK can be Norway (high access, low sovereignty) or it can be Canada (low access, high sovereignty). What it cant have is some superior hybrid of both.
IMHO May, the Brexiteers, the Conservative Government and the Uk Electorate needs to understand that.
