The half-brother, Meghan, would not be surprised if she ran to be President of the United States.

The American former actress, 40, who became a member of the British Royal Family when she married Prince Harry in 2018, has made no secret of her progressive politics since her move to California last year.

Thomas Markle Jr, who has the same father as Meghan but hasn’t spoken to her in a decade, told Australia’s New Idea magazine his ambitious sister could certainly make a move for the White House in the future.

‘She obviously has that personality and that determination and drive… it wouldn’t surprise me [if she ran for president],’ he said.

‘I just know, whatever endeavour she endures and puts her hands on, she will do good things. I wish her the best of luck, but absolutely if that’s what she’s going to put her sights on, she’ll go for it.’

Markle Jr, a 55-year-old window fitter from Oregon, added that Meghan always went after her dreams when she was growing up.

Royal biographer Tom Bower said in March Markle was ‘likely’ to launch a U.S. presidential campaign but would ‘struggle’ with the barrage of criticism levelled at politicians because she is ‘sensitive’.

Mr Bower said she would need to learn to ‘take the heat’ if she entered politics because they are the public figures who cop the most backlash from the press.

Speaking to Closer magazine, he added that Meghan would need to be a ‘team player’ and build up an army of loyal staff – something she appears to have experienced issues with during her life as a royal.

“The possibility of Meghan running for president seems possible, and I would even say probable,” he said. He told the publication that he believes that it’s where she sees her going.

Bower, who is well-known for his unauthorised biographies on towering figures such as Boris Johnson or Prince Charles, said Meghan has “all the qualities” needed to be a strong candidate for office. He cited her drive, ambition and self-confidence as well as her public speaking and public speaking skills.

He said that the Suits star had ‘had her time’ in acting and is now aiming to be a politician. Harry and she have’masterminded’ a new California life.

Bower stated that Meghan can get anything done if she wants it. He referred to the multimillion-dollar Spotify and Netflix deals she and Harry, 37, secured, as well the Oprah Winfrey interview that made headlines all over the world because of their explosive claims regarding the Royal Family.

Meghan will have to deal with a’major problem’ if she enters Congress. She is ‘clearly sensitve’ and, while she may think she has had a tough ride with the media, politicians are subject to constant criticism.

Closer was told by Mr Bower that they are probably the most controversial public figures. She would likely struggle, I believe. She would have to learn to take the heat.

He stated that another problem is that the Duchess must be a team player and build a loyal staff to get elected and to run a campaign.

He observed that despite the reports of her staff members leaving and moving on, he didn’t seem able to keep her team together.
