Questions about whether or not Prince Harry would visit cancer-stricken Princess Kate while in London this week have been making rounds recently. However, the decision has allegedly been made for him.

Prince William has issued Prince Harry, who is visiting the U.K. to mark the 10th anniversary of the Invictus, a warning a warning to stay away from Princess Kate, 42, and their three children, Prince George, 10, Princess Charlotte, 9, and Prince Louis, 6, Woman’s Day Australia reported.

It comes after Prince William, 41, has been under tremendous strain for the past few months, juggling caring for his wife and children while also stepping in as his father, King Charles, undergoes treatment for his own illness diagnosis.

Prince William believes a visit from Prince Harry, 39, is the last thing Princess Kate needs after declaring to the world in March that she is battling cancer.

“They have so much to focus on, her treatment, the children, even the King’s health, so he’s not letting Kate expend any more energy on Harry. He will never forgive Harry for everything he has said about Kate, especially in his memoir, when she simply adored him. e betrayal deeply hurt Kate, and William can’t handle seeing her in any further pain,” a royal insider told the entertainment news outlet.

“For now, William’s essentially set up a perimeter around Kate to make sure she’s drama-free. Harry would be insane to try and see her with the way William feels. It would not end well for anyone, nor would it help Kate in any way,” the source added.

Another report describes it as a "no-win situation" for Prince Harry. “He does want to see Kate and has some regrets about how he’s treated her. If he doesn’t, he’ll be slammed for ignoring her, but if he does, he’ll be risking a serious confrontation with his brother,” the informant stated.

Prince Harry is due to give a reading at St Paul's Cathedral to kick off the anniversary celebration, with sources indicating that this trip will be in and out like the previous one, as per BBC. Prince Harry flew to London in February to see his father after receiving a shocking cancer diagnosis, spending the night in a hotel before returning to Los Angeles.

“Back then, he was banned from seeing Kate by the King. Now Kate’s situation is out in the open, he was hopeful this time might be different, but he’s getting a very clear message that, sadly, he’s not welcome anywhere near the Wales family,” the tipster shared.

Prince William has yet to address the claims that he banned Prince Harry from seeing Princess Kate and their kids. So, avid followers of the royal family should take these unverified reports lightly until everything is proven true and correct.
