Now that would be an excellent use of a UWO: pretty much exactly what they're for, indeed.
And in other good news, I saw not just an MP but a Tory MP on the news yesterday, in the context of the Belarus plane-diversion incident, who said that the UK needed to be cracking down on use of UK firms and facilities by Russian semi-gangsters.
Alas my memory is rubbish today and I can't remember his name or if he was talking of Russian govt or oligarchs, but he was definitely highly critical of Russian money floating round the UK.
It's significant that a Tory is pushing is back on this, because they're the current govt. The Russian playbook of recent years has been to support (probably multiple) political parties, then turn round to whoever wins the election and quietly say, "Ahem. We put you here, remember."
It could be overt with Trump, because he's narcissistic and dim and hasn't a patriotic fibre in his body; they've probably had to be a bit more subtle with UK parties, but have certainly been cuddling up to the Tories from all corners.
So it's a big deal to see a Tory publicly call for the Russian establishment to be refused service.
