It has been well established that Russia influenced the result of our EU referendum using social media, the aim being to destabilise the West, but there is another, even more insidious way that our politics have been corrupted.
One of the leading activists against corruption has told LBC that the UK is failing to act because politics is polluted by dirty Russian money.
Bill Browder has been campaigning for the introduction of the Magnitsky Act around the world, which stops corrupt people bringing their ill-gotten money into western democracies.
That law has been passed in a number of countries, including the UK and the US. In the US, there are 150 people on the Magnitsky list. In Canada, there are 70. There are another 70 in Lithuania and 49 in Latvia and Estonia. There are zero in the UK, despite the law being passed.
