Commons will be told to strip Harry and Meghan of their royal titles ‘after the latest episode of the couple’s feud with the rest of the royal family’

Parliament could consider the ‘nuclear option’ of stripping Harry and Meghan of their royal titles under bomb legislation proposed this week.

Conservative MP Bob Seely is introducing a bill that could deny the couple the status of duke and duchess, as the royal family becomes increasingly embroiled in the ‘racism’ row fueled by the couple’s unofficial ‘mouthpiece’.

The Isle of Wight MP wants to amend laws originally passed in the First World War to deny enemy German nobles their British titles. His bill would force the House of Commons to consider making Harry and Meghan regular Mr and Mrs Sussex, at a time when the couple are under increasing pressure to break their silence over inflammatory claims made by author Omid Scobie.

His new book Endgame has reignited the race row when a Dutch translation named the King and Kate Middleton as the senior royals allegedly speculated about Prince Archie’s skin color.

Mr Seely said he had to act over the attempt to use race to smear the royal family, which he called “venomously treasonous”.

Writing in The Mail on Sunday, Mr Seely said that while sources close to the Sussexes have stressed that Harry and Meghan do not support the claims in Scobie’s book, “I suspect few people believe such denials.”

The politician, who is a member of the House of Commons Foreign Affairs Committee, added: ‘Of all the harmful insults, ‘racism’ is the most toxic, insidious, guaranteed to leave a tinge of stigma and impossible to prove if false. It is the all-encompassing stain of modernity.”

He is asking for his Titles Deprivation 1917 Amendment Bill to be included in the Commons’ Order Paper next week. It would reinvigorate the war powers by removing references to “enemies” and “current war.” He approved the wording with Parliament’s Table Office, which oversees the draft legislation.

Politicians normally shy away from royal controversy, but the inflammatory nature of the ‘racism’ claims has led to rare condemnations. Tom Tugendhat, the Security Secretary, has praised the “dignity” of the King and Princess of Wales, labeling the claims as “rumor and nonsense”.

Harry and Meghan can no longer use His and Her Royal Highness under the 2020 deal in which they gave up their official royal duties. A Mail on Sunday poll this year found that 51 percent of people think their duke and duchess titles should also be revoked.

The King is expected to consult Prince William this week to discuss his response to the storm, after Buckingham Palace said it is “considering all options” when it comes to a response.

But it is clear that a formal meeting is not yet on the agenda. A royal household source told this newspaper: “They will no doubt meet to discuss how best to approach and respond to the fallout from the rather tiresome Scobie affair.”

The row surrounding the royal family first broke out more than two years ago, when the Sussexes told talk show host Oprah Winfrey that a member of the royal family had made comments about their son’s skin color before he was born.

The English edition of Scobie’s book states that Meghan mentioned who allegedly made the comments in a letter she sent to Charles, but did not name names – however, the king and Kate were identified in the Dutch version.

Mr Scobie told BBC Newsnight that he was ‘hurt’ and ‘frustrated’ by the week’s events, but added: ‘It’s not for me to apologize because I still want to know what happened happened.’

The Daily Mail reported yesterday that Buckingham Palace was investigating who could have seen the letter from the end – probably just a ‘small handful’ of people. There is said to be ‘extreme confidence’ that the leak did not come from them.

The Sussexes have not commented publicly, but a source close to Meghan told the Daily Telegraph that “it was not leaked to Scobie by anyone in her camp.”

Meanwhile, Ms. Markle’s estranged father, Thomas, has waded into the controversy.

The 79-year-old – who fell out with his daughter after details of a letter she wrote to him were leaked by her friends – said: ‘Here we have another letter from my daughter that has somehow ended up in the public domain has ended up. Another letter? Again?

“The fact that Harry and Meghan have not publicly distanced themselves from this seems unusual to me.”

Meghan sued The Mail on Sunday after the newspaper published excerpts from the letter to her father.

Mr Seely’s bill is formally entitled ‘a bill requiring amendment’ [the Act] to deprive princes of their British dignity and titles under certain circumstances’. The original 1917 law allowed the Privy Council to prepare a report on British nobles suspected of aiding the enemy.

If neither the House of Commons nor the Lords made a motion to oppose it within forty days, the report would be submitted to the Monarch and the person concerned would lose his title.
