Investigation finds groups hosting Islamophobic attacks on London mayor Sadiq Khan, white supremacist slogans and antisemitic conspiracy theories
Conservative party staff and activists are secretly operating a network of Facebook groups that have become a hotbed of racism, misinformation and support for criminal damage.
An investigation has identified 36 groups that appear to be separate grassroots movements opposing the expansion of ultra-low emission zone (Ulez) schemes to reduce air pollution. They do not say they were set up by the Conservatives as part of a coordinated political campaign.
