Prince Harry and Meghan Markle fear possible terrorist attack at children's school following UK return

Prince Harry and Meghan Markle ’s return to the UK has placed renewed attention on a problem the couple has struggled with for years: how to give their children a normal life while managing an unusually high-profile security risk.

Prince Archie , seven, and Princess Lilibet , five, are due to begin prep school this month, meaning the family could soon be following regular routes and schedules that are far harder to conceal than a private residence or one-off public appearance.

There's no publicly known active terror plot against the Sussexes. Security specialists, however, say routine itself can become a vulnerability when the people involved are globally recognizable.

“From a protection perspective, taking children to and from school presents a very different challenge from securing a private residence or a controlled public engagement,” one security source told RadarOnline.com.

“You potentially have the family leaving at broadly predictable times, traveling along recognizable routes and arriving at the same destination repeatedly.”

Predictable routines create different kind of risk

The concern isn't that an attack is expected, but that protection teams must plan around possibilities before a specific threat emerges.

“Any routine like that has to be examined extremely carefully because predictability can create vulnerabilities that simply don't exist when movements are constantly changing,” the source said.

Harry ’s military past adds another layer to those calculations. The Duke of Sussex served in Afghanistan and wrote in his 2023 memoir, Spare, that he had killed 25 Taliban fighters.

Security experts quoted in the report said that history could make him a symbolic target for an extremist or a lone individual acting on a personal fixation.

“That doesn't mean intelligence agencies have evidence of an active plot,” another source said, “but it is a scenario security professionals cannot afford simply to dismiss.”

The same source suggested that lone actors can be especially difficult to detect because they may have no connection to a larger organization and leave fewer warning signs.

School question brings wider security battle into focus

The issue also ties directly into Harry ’s long-running dispute over the level of taxpayer-funded police protection available to him and his family in Britain.

Since stepping back from duties as working royals, Harry and Meghan have repeatedly argued that adequate security is central to whether they can spend significant time in the UK with Archie and Lilibet .

“The difficult balance is allowing the children to have something resembling an ordinary school life while recognizing that their father's circumstances are anything but ordinary,” the first security source said.

Keeping the school’s location private may also prove difficult over time. Once a routine becomes known, security teams would have to assume that information could potentially reach anyone, including someone with hostile intentions.

That doesn't mean Archie and Lilibet are under a specific threat today. What it does mean is that a normal childhood milestone, starting school, could require a level of planning most families would never have to consider.
