This is an interesting piece on the Lugano Convention. I'm sure that leavers will be falling over themselves to agree with its statement "The EU's pretence that the UK is a third-country like any other is a misrepresentation of reality."
To me, it shows the time is ripe to ditch Frost and replace him with someone who genuinely wants to build a strong relationship with the EU.
