"EU will ban UK from cutting tax or scrapping regulation as price of trade deal"
Blatant extra-territoriality. Which no democratic government could sign up to. So, no deal.
We then take an axe to taxes and regulations and trade with the EU on WTO terms. The EU gets a well run offshore financial center and low tax free market economy just offshore.
So, Mr Tusk, that's fine by me.
(And of course, for us on here, if we can move toward an LVT based tax regime....game over)
Update
On thinking about this it is proof that the 'single market' is not about free trade but all about protectionism.
