The new agreed understanding (regarding the implementation of the WA customs checks) from a day or so ago is funnily enough the exact same agreement that Boris and then Irish Taoiseach Leo Varadkar had agreed October 2019. In the interim, we had all these funny shenanigans about ignoring international law, and Downing Street claiming all sorts of disingenuous moves and manoeuvers by the EU -- all of which seem to be British tactics or strategies in some way or other... Although what these British strategies are achieving, nobody in the EU is quite sure.
Boris recently said that there would be an Irish Sea Border "over my dead body." Well, now there is. The Tories are trying to spin it as something else, but that is just semantics. An interesting segment on Sky News this morning asked a logistics professional if it constitutes a customs border and he said absolutely.
'Boris said over my dead body!' Michael Gove squirms as Brexit deal surrender exposed
You gotta hand it to Gove. He's utterly useless, but he's at least still able to argue black is white.
Separately, there is great suspicion in EU that Boris' visit with Ursula von der Leyen is more of the British theatrics we've seen so many times from the UK government over the past 4 years, and that effectively Boris is laying the grounds to return and say "look, I tried! Its those pesky Europeans who won't accept how Great we are in Great Britain"... The EU isn't interested in playing that blame game.
It has to be said that a deal looks increasingly less likely. This is nothing more than Boris' metaphysical conundrum of having a cake and eating it coming to fruition... Eventually the laws of physics were going to win out.
