The BBC has vowed to defend itself against the $10bn lawsuit that the US president, Donald Trump filed against it.

In a complaint filed on Monday evening, Trump sought $5bn in damages each on two counts, alleging that the BBC defamed him, and that it violated Florida’s Deceptive and Unfair Trade Practices Act.

Trump alleged the broadcaster “intentionally, maliciously and deceptively” edited the 6 January speech he gave before the attack on the US Capitol.

The BBC has previously acknowledged the editing was an “error of judgment” and apologised to Trump, but insisted there was no legal basis for a defamation claim. Tim Davie, the BBC’s director general, and Deborah Turness, the head of BBC News, resigned over the controversy last month.
