King Charles is “tiring” of Prince William and “wants to re-embrace” Prince Harry, a royal author has claimed.

Tina Brown, writer of the bestseller, The Palace Papers, and former Vanity Fair editor, made the claims about the king and the two princes in a new essay, published by the New York Times.

Prince Harry’s return to the UK

Brown said that she believes Prince William, 43, is upset over the success of his younger brother’s recent trip to the UK.

Earlier this month, Prince Harry, of course, made his much-anticipated and widely-publicised trip across the pond.

Here, he appeared at various charity engagements and awards ceremonies and made headlines as he announced a significant personal donation to BBC Children in Need.

‘It’s understandably enraging for William’

He even concluded his visit with an unexpected trip over to Ukraine, upon the personal invitation of the Ukrainian Prime Minister. There, he met with war veterans, and paid his respects to victims of the conflict with Russia.

Reflecting on this, Brown claimed: “It’s understandably enraging for William to see his treacherous younger brother, who spent the last five years trashing his family on TV and promoting a back-stabbing, best-selling book, bounding around the British charity circuit, doing a well-received side-dash to Ukraine and upstaging the photo ops of William’s own diligent engagements.”

Charles ‘desperately misses’ Harry

After months of speculation, the Duke of Sussex also met up with King Charles while in the UK.

For the first time in 19 months, the father and son reunited. They enjoyed a private tea together at Clarence House, Charles’ London residence.

Earlier this year, Harry had expressed a desire for reconciliation with his family. A few months later, senior aides to King Charles and Prince Harry were pictured meeting in London. This fuelled hope of putting an end to the pair’s reported rift.

However, Charles and Harry’s Clarence House meeting is believed to have lasted less than an hour.

Charles desperately misses his prodigal son

Brown nevertheless claimed: “Charles, I am told, is tiring of his elder son’s self-righteous intractability in the family feud, and wants to re-embrace Harry – if only he can keep his mouth shut.”

Reversing the heir/spare narrative, she continued: “It’s no secret that Charles desperately misses his prodigal son who, in earlier days, was always the fun, ebullient scamp compared with the haughtier, more Hanoverian William.”

The comments come amid recent reports that the king will not allow his youngest son to be a “part-time” working royal.
