Prince Harry, Meghan Markle Get "Cast Iron Assurances" of Protection as They Arrive in UK with Archie and Lilibet To Attend Platinum Jubilee

The royal family has allegedly given Prince Harry ironclad promises that he, his wife Meghan Markle, and their two children would be protected by police when they arrive in the UK on Wednesday to celebrate the Queen's Platinum Jubilee.

According to the Mirror, the Duke and Duchess of Sussex, their son, Archie, 3, and daughter, Lilibet, who turns one on Saturday, will fly from their home in California with their special security officers.

They will be protected by the Metropolitan Police's Royalty and Specialist Protection Unit once they arrive on British territory, according to an arrangement that took weeks to finalize.

The arrangement, according to the Mirror's royal editor, calls for the 37-year-old duke and his family to be guarded by specially trained Met cops only while staying at their Windsor residence, Frogmore Cottage, or attending official engagements commemorating Queen Elizabeth II's 70th year on the throne.

If the jet-setting pair chooses to attend any private events during their vacation, they will need to make their security arrangements and pay for them. It will be Meghan Markle's sole visit to her husband's homeland in more than two years when the pair provoked a global uproar by abandoning their royal responsibilities in 2020 and traveling to California through Canada.

The visit comes less than three months after Prince Harry filed a lawsuit against the British Home Office for refusing to allow him to pay for police security while in the UK, claiming that Met policemen were not firearms for sale.

His legal team stated at the time that the duke has been unable to bring his former Suits star wife and children to visit his family because it is too dangerous without police protection, and their private security team from California lacks proper jurisdiction abroad, as well as access to intelligence resources.

As part of a four-day national celebration, Prince Harry and Meghan Markle are set to attend the Queen's Thanksgiving Service at St. Paul's Cathedral in London on Friday, followed by the BBC's Party at the Palace on Saturday. The 96-year-old grandmother of Prince Harry has not seen her great-grandson, Archie, since he was a newborn, and she has never seen her great-granddaughter Lilibet, who was called after Queen Elizabeth's childhood nickname, New York post reported.
