This fulsome investigation by journalists from across the political mix concludes that Ofcom has failed to prevent a single TV channel from becoming the voice of one party. This is of course in full breach of the licensing rules for UK television channels. It is a long read but the first few paragraphs sum it up. In short, GB News is near completely the voice of Reform UK - promoting its views, its scaremongering stories and its politicians.
This is not America where channels like Fox News and Newsmax are free to promote one party or one movement or even on politician. The UK has strict rules on impartiality.
