Prince Harry is offering an olive branch to royal family — but not getting much response

Prince Harry is attempting to mend fences with his family — and has invited them all to the Invictus Games 10-year celebration ceremony in London, multiple sources tell Page Six.

However, no senior members of the royal family are expected at the event at St Paul’s Cathedral on Wednesday.

His sister-in-law Kate Middleton is currently undergoing cancer treatment away from the public eye, and Harry remains estranged from his older brother, Prince William.

As Page Six previously revealed, Harry, 39, has not spoken to his brother, 41, for more than a year in the wake of his bombshell memoir, “Spare.”

A well-placed London socialite who knows the brothers confirmed that Harry had invited William — as well as other members of the royal family — to the event to honor the veterans charity he founded.

It’s still unknown whether Harry will see his father, King Charles, who is also undergoing cancer treatment. Buckingham Palace would not comment on private meetings.

As we reported, Charles is expected to invite Harry and wife Meghan Markle to Balmoral castle in Scotland this summer so he can see his grandchildren Archie, 4, and 2-year-old Lilibet.

Harry and his father last saw each other in February when Charles, 75, was diagnosed with cancer and Harry jetted over from California to see him — but was given just over 30 minutes with the king.

As the Telegraph reported, on Wednesday — the day of Harry’s event — Charles will have his weekly audience with UK Prime Minister Rishi Sunak before attending the first Buckingham Palace garden party of the season, medical advice pending.

He is also understood to have a packed diary next week. It’s expected Harry will not travel to the UK until after Archie’s birthday celebrations; the young prince turns 5 on Monday.

Still, we are told, Harry has invited his family to the event celebrating a decade of his charity which helps wounded servicemen and women.

As he told ABC News in February, he was “grateful” for the time spent with his father earlier that month, adding, “I’ll stop in and see my family as much as I can.”

It’s still unknown whether his cousins — Princesses Beatrice and Eugenie, and Zara Phillips, all of whom he remains close to — will attend the celebrations.

Harry will be staying in a hotel in London, as he no longer has a UK home after being asked to give up Frogmore Cottage on the Windsor estate.

He will be without Markle. Later this month, the couple, without their children, will fly to Nigeria for a tour in connection with the Invictus Games.

There had been rumours the Sussexes would take cameras with them to Africa for a new Netflix project, but Page SIx is told the trip will not be recorded.

Markle, 42, revealed in 2022 that she had discovered she was “43% Nigerian” after doing a genealogy test.

Last month, Harry and Markle were together at the Royal Salute Polo Challenge to Benefit Sentebale, in Wellington, Florida. AP

The couple were invited to the West African country by Chief of Defense Staff General Christopher Gwabin Musa.

The cost of their security is set to be paid for by the government of Nigeria, according to reports.

While in Nigeria they are expected to meet with officials, veterans and athletes participating in the Invictus Games.

The Sussexes’ itinerary is said to include visits to military rehabilitation centers and sports facilities, as well as meetings with local organizations working to support veterans’ welfare.
