Will Harry's return heal rift with his brother? Don't hold your breath

For the past six years Prince William and Prince Harry have practically and emotionally been oceans apart.

But with the Sussex family moving back to the UK , will the closing of the physical distance help ease the anguish and fix the angst between William and Harry?

Harry and Meghan are experts in surprise - but why are they returning to UK now?

This isn't a regular sibling fallout. It is a deep-rooted fracture filled with anger, resentment and a total loss of trust.

The Prince of Wales remains in no mood to forgive and forget. The hurt he feels lingers.

"William is very stubborn," a family friend told the BBC. "To feel cheated by your own brother has been painful. He can't just put it behind him."

But in his interview with the BBC last year , Harry offered a different view.

"I would love reconciliation with my family. There's no point in continuing to fight any more."

The problem for Prince William now is proximity. Harry will be in the UK within two weeks, probably a short drive away from Windsor where William's family lives.

There will be pressure on the elder brother to take the lead, ease the pain and just make up with Harry now the siblings will be living in the same country.

"I think William doesn't care about the pressure to reconcile," said royal author, Valentine Low. "If he doesn't want to reconcile with his brother because of the things he's done, the wrongs that he feels Harry's done to him, he's not going to reconcile. But it does improve the chances I think."

The Prince of Wales will prioritise his public work in the coming months and try not get drawn into the drama around the UK return of the Duke and Duchess of Sussex.

Several people from organisations who have worked with Prince William told BBC News of their desire to support William and help avoid Harry and Meghan becoming a distraction.

One source, who has worked on charity projects with the Royal Family, described wanting to protect the future King.
