The royal pair have reportedly been seen out together socialising and Mehgan gave Kate and William a tour of their new Frogmore Cottage pad, in Windsor.
The brothers’ relationship is claimed to have became strained last year but now a reorganisation of the Royal households is believed to be behind the end to the rift.
Ill-feeling was claimed to have been sparked by William’s doubts over whether Harry was being too quick to marry Meghan last May, less than two years since they met.
They put that behind them ten weeks ago, Royal sources have said, ahead of the imminent birth of Harry and Meghan’s first child.
A new arrangement is in place where Harry will have a new office at Buckingham Palace and William will be based at Kensington Palace.
“Finalising plans on their future paths and roles did make things easier,” a source told the Mail on Sunday.
“There was no formal process or meetings required. It was never that bad. They worked things out between themselves.”
While they admitted that the relationship had been “strained” they have been “back on track for a while now”.
The source continued: “They are in regular contact, which is the main thing.”
Harry and William have been seen getting on well together with friends.
On Easter Sunday, Harry and Meghan showed William and Kate around their new Frogmore Cottage.
The meet-up took place shortly before William headed off to New Zealand to offer his condolences in person to those affected by the Mosque shootings.
Kensington Palace have been approached for a comment.
