William and Kate are under stress while Harry uses the break-in at Windsor Castle to prove his point

Prince William and Kate Middleton reportedly fear Prince Harry will mention the break-in near their Windsor Castle home, Adelaide Cottage, in his British security row.

William and Kate were reportedly left terrified after masked robbers scaled a six-foot fence and stole vehicles from Shaw Farm on the grounds of the royal residence.

Although protective measures have been put in place, the royal family believes that the Duke of Sussex will use this incident to demonstrate his stance on security concerns in the country.

Harry recently said that he would not bring his wife Meghan Markle to the UK due to security concerns, and he is now expected to use this security fear to argue that the UK is not as safe as some claim.

A source said on this topic Closer Magazine“There is some anger that the raid on Windsor Castle took place because it gives the Sussexes ammunition to argue that the UK is not as safe as some might say.”

They added: “This supports Harry’s theory and there are fears that the Sussexes may use this recent incident as part of their argument.”

“But ultimately, what’s most important to William and Kate is that everyone is safe, and they’re just grateful for that more than anything.”
