Prince Harry and Prince William are reportedly working on repairing their relationship as brothers after an intense year.

An insider confirmed to Us Weekly that the British brothers have made strides to repair the relationship, but have a long way to go.

“William and Harry’s fallout was very real, very ugly and incredibly intense,” the insider told the outlet.

“They’d reached an impasse, there was so much mud under the bridge and a lot of people felt their feud was beyond repair.”

Things allegedly escalated after Prince Harry confirmed that himself and his brother were on "different paths" back in 2019, but the height of the fallout was when Prince Harry and Meghan Markle stepped away as senior members from the British royal family.

“Part of this role and part of this job, this family, being under the pressure that it’s under, inevitably stuff happens,” Prince Harry said at the time in ITV's 2019 documentary Harry & Meghan: An African Journey.

“But look, we’re brothers, we’ll always be brothers. We’re certainly on different paths at the moment but I’ll always be there for him and I know he’ll always be there for me.”

The insider claims it has been a "rollercoaster".

“It’s certainly been a roller coaster for everyone involved, especially the brothers, who are vowing not to let things get this out of hand in the future and have learned a lot from this difficult experience,” the insider said.

The insider also alleged that the pair, once border restrictions are lifted, are planning to reunite in England.

“(William and Harry) are looking forward to spending time together in person the moment it’s safe to travel,” confirmed the insider.

Royal historian and biographer Robert Lacey agreed that the brothers had a fight as "royals are expected to know their place".

“Royals are expected to know their place,” Lacey continued.

“And Harry, of course, was expected to marry a nice girl named Henrietta or Gabriella who lived in the provinces of Britain in the countryside and settle down. But Meghan and Harry both made it clear they wanted to do so much more than that. And let’s just say there are things that you can and cannot do when it comes to running the royal family and what it stands for.”

He also agreed that their relationship would take some time to heal.

“I think it would always have happened that Meghan and Harry would live on the other side of the world,” he said. ”I think Meghan and Harry will remain based in North America. Unless the brothers can find a way to reconcile, they will have to go their separate ways and keep mutual respect for each other.”

“We do know that in July 2021, both brothers have committed to being in Kensington Gardens for the unveiling of the statue dedicated to their late mother, Princess Diana,” he pointed out.

“The world will judge then. But there is a lot of work to be done.”

It is currently unknown whether the statue unveiling will go ahead due to the coronavirus pandemic and current travel restrictions.
