What began as a carefully staged charity polo appearance in support of Sentebale has since taken on far greater significance, after newly released footage appeared to capture the moment a quiet but consequential rift between Prince Harry and the charity’s chair Sophie Chandauka first surfaced in public view — a dispute that is now unfolding in the High Court and drawing scrutiny from regulators.

The full video, published for the first time by Hello! magazine, shows an awkward exchange involving Meghan Markle and Dr Chandauka during a trophy presentation at a charity polo event in Miami in April 2024. At the time, the moment passed without public explanation. But with Sentebale now pursuing a defamation claim against Harry and his longtime friend and former royal equerry Mark Dyer, the footage has been reinterpreted as the earliest visible sign of tensions that would later escalate into a high-profile legal confrontation.

The clip captures Meghan stepping onto a trailer stage to present a silver polo trophy to her husband after his team’s victory at the Royal Salute Polo Challenge. After greeting him with an affectionate kiss and handing him the trophy, she appeared to direct Dr Chandauka — who had approached from Harry’s right — to reposition herself on the other side of the couple. The request forced the charity chair to duck awkwardly beneath the trophy as she moved across the stage to comply.

Dr Chandauka smiled politely at the time and no disagreement was visible during the ceremony. Yet the interaction would later become central to her account of events surrounding the day. Speaking months afterward, she said Meghan’s unexpected arrival at the event had disrupted the carefully planned stage choreography and contributed to confusion during the presentation.

According to Dr Chandauka, she had not been informed in advance that the Duchess would attend the Miami fundraiser. Meghan instead arrived alongside tennis legend Serena Williams, a close personal friend, shortly before the ceremony began. While her appearance generated excitement among attendees and media interest, it also meant additional people were present on stage during the trophy presentation than organisers had anticipated.

Dr Chandauka later explained that the resulting congestion on stage created uncertainty about positioning and timing during the presentation, drawing attention from international press photographers and prompting widespread discussion online about whether the Duchess should have been standing where she did.

The situation might have remained a fleeting moment of awkward staging were it not for what followed in the months afterward. Dr Chandauka later revealed that Harry had asked her to issue a public statement supporting Meghan after criticism of the incident emerged. She declined, explaining that she believed it would be inappropriate for the organisation to appear aligned with the Sussexes’ personal image management.

Her refusal, she said, was not intended as a slight against the Duchess but reflected a broader concern about maintaining Sentebale’s independence as a charity rather than allowing it to become associated with any individual public figure.

That disagreement appears to have marked a turning point in relations between the charity’s leadership and its royal co-founder. Over the following months, tensions escalated as disputes emerged over governance decisions, organisational priorities and financial oversight within Sentebale’s management structure.

The disagreement widened further when members of the charity’s board challenged Dr Chandauka over a reported £400,000 consultancy bill that trustees believed had delivered limited measurable benefit. She was asked to step down from her position but instead raised concerns with the Charity Commission, alleging bullying, misogyny and racism within the organisation’s leadership.

Those allegations were strongly denied by Harry and others involved in the charity’s governance. Following an investigation, the regulator said it had found no evidence supporting claims of racism or bullying. However, it did criticise governance practices within the organisation and warned that the dispute had been allowed to become unnecessarily public, potentially affecting the charity’s reputation and operations.

As tensions continued to intensify, trustees — including Harry and Mark Dyer — resigned en masse in March last year. Harry and his co-founder Prince Seeiso also stepped down as patrons of the charity they had established together in 2006 in honour of Harry’s late mother, Princess Diana, to support young people living with HIV and Aids in Lesotho and Botswana.

Their departures marked a dramatic turning point in the organisation’s history and signalled the depth of the breakdown between the charity’s founding leadership and its executive structure.

Since then, the dispute has escalated into formal legal proceedings. Sentebale has launched a defamation lawsuit at the High Court against both Harry and Mark Dyer, alleging libel and slander connected to statements made during the leadership conflict.

The decision to pursue legal action has itself drawn scrutiny from regulators. The Charity Commission confirmed that it had been in contact with Sentebale’s trustees after learning of the charity’s intention to sue its own founder earlier this year. Officials are now seeking clarification on how pursuing the case supports the organisation’s charitable objectives.

A source close to Harry has argued that, regardless of whether the legal costs are funded externally or internally, resources associated with the dispute could otherwise have supported the charity’s core mission assisting vulnerable young people in southern Africa.

Sentebale’s trustees, however, have insisted that the legal action is being financed entirely through external funding rather than charitable donations. They said they believed supporters of the organisation would understand why pursuing the case was necessary in order to protect the charity’s integrity and long-term effectiveness.

Dr Chandauka has also linked the dispute to wider concerns about the impact of Harry’s public profile on the organisation’s operations. She claimed the “toxicity” surrounding his media image had begun affecting partnerships and fundraising efforts connected to Sentebale’s work.

Among the issues she raised was a request, made shortly before the Miami polo event, for a camera crew associated with one of Harry’s Netflix projects to film footage at the fundraiser. According to Dr Chandauka, organisers had concerns about obtaining consent from sponsors, venue owners and guests who had not agreed to appear in a commercial production.

She said the venue ultimately introduced additional conditions after learning of the filming plans, creating financial complications that the charity was unable to accommodate.

Representatives for Harry and Mark Dyer have rejected Dr Chandauka’s allegations, describing them as “offensive and damaging.” The legal case now underway at the High Court is expected to determine whether the statements at the centre of the dispute meet the legal threshold for defamation.

Meanwhile, the resurfaced Miami polo footage continues to attract widespread attention online, with millions viewing the exchange between Meghan and Dr Chandauka as observers search for clues about the origins of the dispute.

In hindsight, what once appeared to be a minor moment of stage confusion has come to be seen as the first visible sign of a breakdown in relations between Harry and the leadership of the charity he founded nearly two decades ago — a disagreement that has since grown into one of the most serious public conflicts of his post-royal life.
