Is Russia targeting Poland's farmers’ protests?

Farmers' protests have been erupting across Europe, and on February 20th one image from a protest in Poland went viral. It showed a tractor carrying a soviet flag and bearing a slogan calling on Russian President Vladimir Putin to ‘bring order to Ukraine, Brussels and our rulers.’ The man driving the tractor was arrested and is currently awaiting trial. After the image was released Poland’s foreign ministry spokesperson released a statement warning of attempts to take over the country’s agricultural protest movement by extreme and irresponsible groups ‘possibly under the influence of Russian agents.’ In this episode of BBC Trending, we attempt to track down the man behind the banner. Who is he? And what’s the evidence for Russian involvement in, or amplification of, farmers’ protests in Poland and beyond?
