A significant feud between Prince Harry and the leader of a charity he helped establish, has intensified following accusations by the leader, Sophie Chandauka, claiming that the prince engaged in harassment and intimidation tactics in an attempt to force her out of her role.

Ms. Chandauka stated that when Harry abruptly resigned from the charity, Sentebale, which he co-founded, it was strategically done to harm the organization after failing to remove her from her position as the head of the board of trustees.

“Can you imagine the impact that attack has had on me, personally, and on the 540 individuals affiliated with the Sentebale organizations along with their families?” Ms. Chandauka expressed in an interview with Sky News. “This is a clear example of harassment and bullying on a large scale.”

A representative for Harry and his wife, Meghan, chose not to respond to Ms. Chandauka’s recent allegations, which she made in the Sky News program “Sunday Morning with Trevor Phillips.”

Established by the prince in 2006, Sentebale aims to honor his late mother, Diana, Princess of Wales, and is dedicated to providing support to young individuals affected by the H.I.V. pandemic in Lesotho. Their operations have since extended to Botswana, focusing on issues such as substance abuse, gender-based violence, and climate change.

Harry, titled the Duke of Sussex, announced his resignation last Wednesday, alongside the charity’s co-founder, Prince Seeiso of Lesotho, citing the irreparably damaged relationship between the board of trustees and Ms. Chandauka as their motive. Earlier that week, five out of nine board members had stepped down.

These departures came in the wake of ongoing disputes between the board and Ms. Chandauka, with the five members expressing their lack of “trust and confidence” in her leadership.

“It is both shocking and heartbreaking that the relationship between the charity’s trustees and the chair of the board deteriorated to a point of no repair, leading to this unforeseen situation,” Harry and Prince Seeiso jointly stated upon their resignation. “We remain deeply committed to Sentebale’s beneficiaries and are exploring ways to continue supporting them.”

The disagreement between board members and Ms. Chandauka has now been taken to an English court and Britain’s Charity Commission, which oversees charities in England and Wales. Both parties have accused each other of misconduct. Sentebale, although primarily operating in southern Africa, is registered in the UK.

Ms. Chandauka, a Zimbabwe-born lawyer who has worked with Morgan Stanley and Meta, took up the role of Sentebale’s chair in July 2023, a position she previously held as a trustee from 2009 to 2015.

Among the mismanagement allegations made by Ms. Chandauka against Harry was an incident captured on video following a charity polo match in Miami last April. Meghan appeared to request Ms. Chandauka to switch spots where she stood next to Harry during an awards ceremony on stage. This led news outlets to scrutinize Meghan’s actions.

“Prince Harry requested I support the duchess publicly, but I declined. Not because I don’t care for the duchess, but knowing well the repercussions that could have. Secondly, because we cannot act as extensions of the Sussexes,” Ms. Chandauka stated. “The venue of the polo match had to be changed since Harry insisted on bringing in a Netflix camera crew for his documentary, with whom the couple has a deal.”

Ms. Chandauka believes the controversy surrounding Harry and Meghan’s estrangement from the royal family poses the greatest threat to the charity. As the tensions grew, she stated she became a target of “the unleashing of the Sussex machine,” referring to Harry’s public relations team.

Despite her complaints, Ms. Chandauka generally characterized her relation with Harry as “fantastic.” She asserts, “There are individuals on the board who seemed to believe they could mistreat a woman with impunity.”
