The UK has already agreed far stricter terms than any other FTA the EU has agreed.

The demand last week to try and exclude the EU from following terms it has ironically spend the last year referring to as the "Level playing field" will result in the collapse of the talks.

This isn't anything to do with sensible economic policy, the EU has never demanded anything like this in any FTA and it exists in no other FTA in the world.

This is about deterring other country's from leaving the EU because the EU has realised that a normal FTA would be seen by many country's superior to EU membership.

The UK should absolutely go no-deal at this point and focus on putting tariffs in place that force industry's that have relocated to the EU over the last 40 years to relocate back to the UK. Its hard to lose a trade war when your opponent runs a trade surplus with you.
