In a clip to promote the interview, Mr Carlson claimed that Mr Morgan was “banished” from UK television for “asking a simple question”.
“I still don’t believe what they were saying, and in particular, I don’t believe what Meghan Markle was saying,” Mr Morgan said in the interview, which aired on Fox Nation, Fox News’ subscription-based streaming service.
On 9 March Mr Morgan said he “didn’t believe” a word the duchess said in the interview.
