Breaking new : Harry charity engulfed by cash fears, insiders claim…See More

Financial worries and disagreements about fundraising helped inflame the row that has engulfed the charity founded by Prince Harry, insiders close to former trustees told BBC News.

An acrimonious boardroom battle has seen Prince Harry, his co-founder Prince Seeiso of Lesotho and trustees resign from their roles at the charity and insiders claimed personality clashes and tensions around leadership of the charity added to Sentebale’s challenges.

The financial fears were despite the charity receiving an extra £1.2m from Prince Harry’s earnings from his best-selling memoir Spare.

Sentebale said it had successfully hired consultants to find new US donors – and the one-off money from Spare was “incredibly useful” but did not represent a long-term “funding pipeline”.

The claims and counter-claims over Sentebale are set to be examined by the Charity Commission, which will have to decide whether to escalate the concerns to a full statutory inquiry.

The watchdog is likely to hear financial concerns from former trustees, who resigned earlier this month after the chair Sophie Chandauka refused to step down.

“It is devastating that the relationship between the charity’s trustees and the chair of the board broke down beyond repair, creating an untenable situation,” said a statement from those trustees leaving the charity.

Among the likely claims are that £500,000 of Sentebale’s money was spent on consultants in a strategy to get donations from wealthy individuals and foundations in the US, but which sources close to former trustees say had not delivered results
