WASHINGTON: A federal judge on Thursday ordered Donald Trump to sit for a deposition by Dec 11 in his US$10 billion defamation lawsuit against the BBC, which has accused the US president of stalling to avoid answering questions under oath, the Associated Press reported.

Trump is suing Britain's publicly funded broadcaster for at least US$10 billion over a misleadingly edited clip of a speech. The case is one of several Trump has privately filed against the news media as part of wider pressure campaign against coverage he dislikes.

US Magistrate Judge Enjolique Lett ordered Trump to take questions from the BBC's lawyers under oath in a ruling from the bench at a court hearing on Thursday, according to the AP. Trump canceled a deposition in October, citing conflicts with his presidential duties.
