Good morning. Where once there was protocol, now there is protocol amended by framework. I’m talking, of course, about the announcement yesterday that the UK and the EU have agreed a deal to end the interminable dispute over post-Brexit trading arrangements in Northern Ireland.

The news was finally announced by Rishi Sunak and EU president Ursula von der Leyen in a highly choreographed, and conspicuously cheery, appearance at Windsor Guildhall – previously better known as the wedding venue for Charles and Camilla, and Elton John and David Furnish.
