Sir Paul is certainly correct in describing the BBC as the propaganda arm of the state. This became apparent during the 'pandemic' when any critical analysis of government policy (lockdowns, masking, social distancing, jabs, throwing free money at anyone who had a pulse and some who didn't) was brutally suppressed. The BBC's left-wing bias is not as blatant however as another state-owned outlet, Channel 4, although naturally the equally left-wing Independent doesn't even mention this.
Nor does it mention the principal reason GB News is losing money, a boycott by mainstream advertisers organised by left wing 'activists'. Should that be allowed in a democracy? All views are valid but some views are more valid than others? The censorship-industrial complex wields huge power in the UK, and Sir Paul is one of the few media owners with the cojones to fight back against its attempt to impose a single, dystopian narrative on world events.
