He then claimed that the couple are “using connections that come with Harry’s royal blood and Meghan’s telly fame, including ITV big wigs via their news presenter BFF Tom Bradby, to scare critics into silence.”
Mr Wootton said he was under pressure from ITV to be more “glowing” about his royal reporting on Prince Harry and Meghan Markle.
Writing in his column in the Daily Mail he said: “There would be hushed conversations with executives outside the ITV studio at Television Centre that always started with something like: ‘Dan, we’re under a lot of pressure.
The royal expert said he was afraid that free speech was being threatened by the “liberal elite”.
He said: “If you’re Meghan McCain on The View in the US or Jane Moore on Loose Women in the UK, it’s going to become increasingly difficult, and professionally risky, to express any view that doesn’t fit with the narrative of the liberal elite.”
He added: “Jane, a friend of mine without a racist bone in her body, was accused of ‘being OK with casual racism’ by her Loose Women co-presenter Charlene White.
“This was for criticising the vagueness of Meghan’s damning allegations about racist language speculating on the skin colour of her unborn baby by a member of the Royal Family.”
Mr Wootton then targeted Meghan Markle’s friend, Omid Scobie.
He said: “And the couple’s hagiographer Omid Scobie, who is drip-fed press releases that he passes off as news, even had the cheek to do down one of our great biographers Tom Bower, whose books on everyone from Boris Johnson to Simon Cowell are essential historically, because of the colour of his skin.”
Mr Wootton, the journalist at the centre of Hollywood star Jonny Depp’s defamation case last year, has left his role at The Sun.
He has taken up a new role at GB News and the Mail Online.
