Meta is abandoning the use of independent fact checkers on Facebook and Instagram, replacing them with X-style "community notes" where commenting on the accuracy of posts is left to users.

In a video posted alongside a blog post by the company on Tuesday, chief executive Mark Zuckerberg said third-party moderators were "too politically biased" and it was "time to get back to our roots around free expression".

The move comes as Zuckerberg and other tech executives seek to improve relations with US President-elect Donald Trump before he takes office later this month.

Trump and his Republican allies have criticised Meta for its fact-checking policy, calling it censorship of right-wing voices.

Speaking after the changes were announced, Trump told a news conference he was impressed by Zuckerberg's decision and that Meta had "come a long way".

Asked whether Zuckerberg was "directly responding" to threats Trump had made to him in the past, the incoming US president responded: "Probably".
