New details of Russian donations to Boris Johnson's Conservative party - Business Insider

While the report did not name donors, it warned that senior Russian figures had used their money to fund British political parties and businesses, with the UK "viewed as a particularly favourable destination for Russian oligarchs and their money."

The report states that the UK government did not seek to find out about potential Russian influence, citing "extreme caution" among UK security officials to look into potential interference by Moscow.

They needed a report for that?

I sniggered a bit when I read that in a UK paper:
The Russian troll factory at the heart of the meddling allegations | Russia | The Guardian

"Of course, if every day you are feeding on hate, it eats away at your soul. You start really believing in it. You have to be strong to stay clean when you spend your whole day submerged in dirt," he said.

Yes, imagine feeding on hate for a living.
On the one hand, of course something like that exists. Russia wouldn't fund an English language TV station if they didn't care to manipulate public opinion. But what are these quotes? Imagine working at a troll farm for minimum wage and clinging to a higher sense of morality than 95% of Facebook pensioners. I also note that they didn't mention that this said troll farm was supposedly run by the head of the Wagner group, which seems to be relevant? But nothing I've seen gives any indication that Russia had any kind of impact on Brexit. And the hyper focus on Russia only serves to to obfuscate the obvious: Brexit was cooked up by the hacks and their owners in conjunction with factions in the Tory party. And little could be done about it because the sensibles prioritized their factional infighting in the Labour party.
