Interesting.
Farage will obviously have picked up on the phrase "patriotic recoil" that has descended upon the Musk situation and will be well aware that despite the media portrayal of the UK government as evil incarnate, the vast majority of the UK really do not like and will not put up with any foreigners sticking their nose into the UKs business. And if anyone knows about that it's Nigel Farage.
I think the best way to view things currently is a blender with blades-a-spinning that will happily slice through anything and anyone that misses their rhythm and fails to drop through cleanly.
Obviously if Mandelson is a fucking useless as Musk told Trump, then there is no reason for Trump to worry is there ?
Of course it may be that Mandelson was actually a stalking horse for a candidate of a different stripe.
If Mandelson is approved, it will be because it was a brilliant idea of Donald Trump for the UK to send a politician rather than a diplomat. And I am sure Keir Starmer will thank him personally for his advice.
