There are indeed many reports from independent sources, not the mainstream Tory supporting newsmedia, who have also received Russian money.
The Daily Telegraph also known as the Torygraph supposedly received £250,000 from Russian oligarchs, as did many Tory MP's in their individual constituencies. Some £2.5million has been spread around the constituencies. Independent news media has reported on Lebedev Senior's closeness to Putin https://bylinetimes.com/2022/03/15/lebedev-the-kgb-spy-who-helped-put-putin-in-the-kremlin/
and there is also YouTube footage of Lebedev senior boasting of his property investments in Crimea after Russia invaded the Ukrainian area. A politician who actually punched an opponent on live tv.https://www.youtube.com/watch?v=lzO7gIT5GYU
This is Boris Johnson's lack of integrity for you.
