Prince William is said to be "totally tied up" over his ongoing feud with Prince Harry, a royal commentator has claimed.
The rift has allegedly got worse due to Meghan Markle's reported upcoming autobiography, with the Prince of Wales feeling unable to contact his younger brother about it.
The speculation about the Duchess of Sussex's memoir has angered William, according to reports.
But royal author Duncan Larcombe claimed the Prince of Wales has fears over his correspondence with the Duke of Sussex becoming public if he was to ever reach out.

This has only intensified the distance between the brothers.
Larcombe said: “William’s real headache is that he can’t get in touch with his brother without risking the contents of any conversation they have being made public.
“It is a real frustration for him and it totally ties him up.”
He also told Fabulous: “It isn’t just about Harry promoting his book, the podcasts or the Oprah chat, but he has revealed some very personal and private family matters, like when they all rallied around the Queen’s bedside (before she died).

“It’s so far over the mark of what the royals would consider acceptable and it just makes it impossible for William to trust his brother or make any move towards (a reconciliation).”
The commentator claimed that the bond between William and Harry has completely broken down.
Larcombe opined: “It’s one thing having a row with your sibling, it’s not uncommon in any family, but in this particular context, it is a constant betrayal.
"William can't make that first move without Harry betraying him and breaking his confidence.
