The former trustees of Prince Harry's African charity Sentebale have told PEOPLE in a statement that they are 'gravely concerned' about the future of the organization following the findings of a probe into the charity going public.

Earlier this year, Sentebale's chair, Dr Sophie Chandauka, used an interview with Sky News' Trevor Phillips to accuse Harry of "harassment and bullying at scale". The prince strenuously denied those claims and has now been cleared by the Charity Commission, which found no evidence to back up Dr Chandauka's accusations.
