Prince Harry, the Duke of Sussex, co-founded the charity Sentebale nearly 20 years ago in memory of his late mother, Princess Diana.

Prince Harry and his co-founder, Prince Seeiso of Lesotho, abruptly resigned this week as patrons of Sentebale, the charity they established in honor of the late Princess Diana.

Harry resigned from Sentebale, the charity he co-founded in memory of his mother, after a dispute erupted between the charity’s chair, Sophie Chandauka, and five of its trustees.
