Notice the last paragraph:
However, he is a controversial character with links to the far-right. In March, Svetov posted a 70-minute interview with British far-right activist Tommy Robinson on his YouTube channel.
This is such a dirty character assassination trick there. I've looked up the interview, and watched it a little bit — in it Svetov has a friendly chat with Tommy Robinson, listening to his opinions, offering his own, disabusing him of his misconceptions about Russia's role in the Ukraine conflict or about Putin, asking him direct questions. It's what a normal conversation between two people from different cultures interested in each other's opinions sounds like. A bit like Joe Rogan, maybe. To say that this interview makes Svetov a "controversial character" is absurd. Is Robinson not deserving of human conversation?
In the interview, they even joke (at 30 min): Robinson says, after this visit to Russia, I'll be called a Russian asset. Svetov says, after this interview, I'll be smeared as an agent of the right wing. Turns out, Svetov was right :-)
