Meghan Markle, Harry's UK relocation 'is going to be challenging' for Prince William, Kate Middleton

Meghan Markle and Prince Harry are relocating to Britain next month, and the royal insiders have claimed that it "is going to be challenging" for William and Kate Middleton.

The OK!, citing the royal sources, has reported that although King Charles would love to have Harry around, "It will be very hard for him and [wife Kate Middleton].

“There is a deep sense of betrayal. It’s going to be very hard for the family to ignore their presence."

The Duke, his wife Meghan Markle and their kids Archie and Lilibet will be moving to England later this summer.

Archie and Lilibet are set to attend school in Britain.

The source told the People on Tuesday King Charles will want to see his sons William and Harry together over time,” adding “This is the best opportunity we have seen in recent years.”

Meanwhile, royal expert Richard Fitzwilliams told Fox News Digital, since the brothers haven’t spoken in years, “the imminent arrival of the Sussexes places William and Catherine in a pressured and difficult situation.”

Fitzwilliams said, "William is reportedly furious. But what is essential is that the king accepts that the Waleses and their children are the future of the monarchy."

Moreover, royal expert Kinsey Schofield doesn’t believe reconciliation between the brothers is likely, at least anytime soon.
