UK police refuse to investigate 600k donation to Tory party. Barclays flagged it as suspicious, the New York Times investigated it and found it to have come from a Russian bank account (500 is the limit for a non-UK citizen, and that's 500, not 500k). The UK police says it's ok. And thus the Tories continue to take Russian money, and they'll continue to be elected on Russian money.

Let's not forget, of course, that the Commons committee found that the authorities saw nothing wrong in the Leave campaign taking Russian money, because they'd been instructed to look away to allow for exactly that argument. The police and the Tory party are in cahoots.
