Honestly, I'm not always the biggest fan of him myself, his tone and approach can be rather grating sometimes, but I guess if you've been calling out the Brexit lies and nonsense for as long as he has, and to be, let's face it, pretty much completely vindicated on every single count - you're going to come across as a bit of an arrogant cockwomble sometimes.
However, he does often hit the nail on the head, as he does in the clip linked above.
I can see Brexit consuming another Tory PM at this rate, as Sunak, like all those before him, comes up across the immovable object of the die-hard loonies in his party who despite having got everything they've wanted so far, are still unhappy and still want to set fire to more things, convinced that the TRUE BREXIT WINS are just around the next corner. Let's blow up the ECHR! One of Winston Churchill's proudest achievements.....
I think it is fair to roll in the whole thirteen years thing too, because Brexit is definitely part of thirteen years of dysfunctional rule, and in particular the ravages of austerity, which rightly made many people very angry,
but they got angry with the wrong thing.
If you get a chance to read it goaty, and you're minded to, I'd really recommend this book, it lays out very clearly how Brexit is inextricably intertwined with the gobsmacking incompetence and corruption of successive Tory governments since 2010. It might actually be quite hard to find a copy at the moment though, as it's sold really well so they're having to do some more print runs.
(It's also very funny too!)
