Charles Howard "Dick" Ellis CMG CBE (1895–1975), was an Australian-born British intelligence officer who is alleged to have also been a double agent for Germany and the Soviet Union.According to Nigel West the SIS believed that Ellis had been a spy for the Abwehr. Ellis was accused by Chapman Pincher of being a traitor. During the 1980s, Prime Minister Margaret Thatcher's refusal to confirm or deny Pincher's allegation caused distress to the Ellis family.
