Remember that Clause One of the Editors Code concerns accuracy, a rather basic requirement of news media, and a legal requirement for broadcast media (but not the self-regulated press of course).
The unsubtle, untrammeled flak (Chomsky filter...) that has seen MPs labelled traitors over Brexit votes carries a strong whiff of fascism. Death threats were received by those government MPs who dared defy government policy, which of course closely mirrors the editorial policy of the right-wing press, especially the Mail - which historically supported fascism, including Britain's own wannabe Hitler, Oswald Mosley.
The short quote of one Tory MP would be a useful one to learn ("newspapers that seem entirely disinhibited in the inaccuracies they peddle“):
"Some of this was fuelled and orchestrated by newspapers that seem entirely disinhibited in the inaccuracies they peddle and the vitriolic abuse they are prepared to heap on those who do anything they consider to be at variance with their version of what Brexit should be. This both obscures the real issues, and encourages an atmosphere of crisis and confrontation between binary positions that leads directly to the death threats that we have received.”
Anna Soubry, another rebel, said such reports fostered a climate of extremism. “That’s the thing that concerns me about all of this. We’re increasingly having a form of politics in which debate is not based on ideas. It’s based on complete and total misconceptions. It’s whipping up a storm by newspapers. It’s poisoning public life.”
