Prince Harry is “heartbroken” to quit his Sentebale charity.

The Duke of Sussex and his co-founder, Prince Seeiso of Lesotho, issued a joint statement Wednesday describing their “devastating” decision.

The duo, who created the African organization in 2006, blamed an “untenable situation” between chairwoman Dr. Sophie Chandauka and the board of trustees.

“With heavy hearts, we have resigned for our roles as patrons of the organization until further notice, in support of and solidarity with the board of trustees,” they continued. “It is devastating that the relationship between the charity’s trustees and the chair of the board broke down beyond repair.”

The royals noted that they launched the charity, which helps young people affected by the HIV/AIDS crisis, “in honor of [their respective late] mothers,” Princess Diana and Queen Mamohato Bereng Seeiso.

The name, notably, means “forget-me-not,” with the pair explaining, “It’s what we’ve always promised for the young people we’ve served through this charity. Today is no different.”
