Britain’s top charity watchdog announced it has launched an investigation into Sentebale, an African charity established by Prince Harry in memory of his mother, Princess Diana.

Prince Harry helped launch Sentebale two years after he took a gap year in Lesotho in 2004 and nine years after the death of his mother, Princess Diana, in a 1997 car accident in Paris.
