Piers Morgan has slammed the Duchess of Sussex in his first interview after being dumped from ITV’s Good Morning Britain after comments he made about Markle’s mental health.

He appeared on US streaming service Fox Nation and spoke with host Tucker Carlson about his departure that came after Markle formally complained about his on-air behaviour.

“I still don’t believe what they were saying,” Morgan told Carlson during the interview.

“And in particular, I don’t believe what Meghan Markle said. Seventeen different claims by the pair of them have now been proven to be either completely untrue or massively exaggerated or unproveable.

“I didn’t believe Meghan Markle, a huge furore erupted through the day – I was an outrage. I wasn’t allowed to have an opinion, that I didn’t believe what she was saying even though it was clear to me in real time as I was watching the interview that there were a number of things which just couldn’t be true.”

Morgan used the interview, which ran for more than an hour, to clarify some of the statements he made on-air.He said that his issue with Markle’s interview with Oprah was that two royal aides rejected her requests for help.

“I was told that you have got to believe Meghan Markle,” Morgan said.

“And if you don’t believe what she’s saying you are a racist.

“I find that impossible to believe, you would have two people in the palace who will be that callus to a woman telling them that she was suicidal.”

Morgan also explained that there was “a lot of anger” in the UK over the timing of the Oprah interview which coincided with Prince Philip spending a month in hospital.

“(There was) A lot of anger building in Britain towards the very ugly smearing of our Queen, particularly at a time when her husband Prince Philip, who’s 99, was fighting for his life in hospital.

“Everything about this was tacky, tasteless, disingenuous and I’m afraid, I believe, in some cases, downright lying on a global scale.”
