Prince Harry visits Oxfam to replace contentious charity boss

As Lynda Chalker, she was the overseas development minister for eight years in the Conservative governments of Margaret Thatcher and John Major. “Lynda brings a tremendous wealth of experience and knowledge in the overseas development arena, with a specific emphasis on Africa,” says Green.

Martin was appointed as Sentebale’s first full-time chief executive scarcely two years ago. She hit the headlines in 2010 when Jo Clarke, the former finance and operations manager of WellChild, the charity of which Martin was previously chief executive, told me that she planned to take legal action.

Clarke claimed that working for Martin had put an intolerable strain on her health and said she was preparing a “personal injury” civil action against WellChild.

During Martin’s period as the chief executive of Sentebale, several prominent figures left the charity. She took the unusual step of occupying one of the vacant seats on the board while retaining her role as its boss.

However, Green, who was appointed last year by the Prince as chairman of Sentebale, which means “forget me not” in Sesotho, pays generous tribute to Martin’s work for the charity.

“We are all very grateful to Kedge,” says Green, the former boss of United Utilities. “Her expertise, dedication and commitment have been behind the charity’s transformation into a dynamic and increasingly effective young organisation, helping save thousands of lives each year.”
