LONDON — The Russian Embassy in London has called the BBC, Britain’s public service broadcaster, a “propaganda and disinformation tool” that was full of “ideological dogma.”

The criticism follows U.S. President Donald Trump threatening to sue the BBC for $1 billion over its editing of a speech he gave on Jan. 6, 2021, during a Panorama documentary broadcast days before the 2024 presidential election.

Writing on Telegram, the Russian Embassy said the BBC was “nothing more than a propaganda and disinformation tool.

“Its journalists select and manipulate facts, as well as censor information that does not align with their partisan editorial stance.”

The corporation has come under fire after a leaked internal memo alleged biases in the broadcaster, which is supposed to remain impartial, over its coverage of the U.S. president, the Middle East, and transgender issues.

The U.S. president’s lawyers have given the corporation until Friday to “retract” any “false, defamatory, disparaging, and inflammatory statements” about him.

Moscow’s London outpost accused the BBC of “systemic flaws … where ideological dogma has replaced journalistic ethics” and claimed there had been years of “biased reporting” and “double standards” in editorial policy.

“The corporation has become a platform for Russophobia and extremism,” the Telegram post said, concluding that those in charge of the corporation “will be held accountable for their Russophobia and compelled to apologize publicly for the years and decades of slander.”

British Culture Secretary Lisa Nandy will give a statement on Tuesday afternoon about the controversy, as well as the corporation’s future funding model.
