Ken Flower (died 1987) was of Cornish extraction and worked for H.M. Customs & Excise before joining the British South Africa Police in Southern Rhodesia in 1937. After war service in British Somaliland and Ethiopia he returned to Rhodesia in 1948 rapidly rising in the hierarchy of the BSAP. He studied the Mau Mau insurgency in Kenya and applied his knowledge in the disturbances in British Nyasaland during the late 1950s.
Flower was appointed Deputy Commissioner of the BSAP in March 1961 and subsequently served as the first head of Rhodesia's and later Zimbabwe's Central Intelligence Organisation. The organisation had been set up by him under Prime Minister Winston Field in 1963 though the original initiative for such an agency had come from Field's predecessor Sir Edgar Whitehead. Flower saw himself as non-political, though with a bias against the 'cowboy element' in the Rhodesian Front, as he dubbed it. Ken Flower has been tied to the creation of RENAMO, a tribally-based guerrilla organization in Mozambique.
He wrote Serving Secretly: An Intelligence Chief on Record, Rhodesia into Zimbabwe 1964-1981, published in 1987.
In 2011 the BBC Radio 4 programme Documents featured proof from Lord Owen, of Britain, that Ken Flower had been an MI6 mole for Britain during his tenure as head of Rhodesian CIO, and that his disclosure of Rhodesian plans had enabled Mugabe to survive assassination and become the first prime minister of Zimbabwe, following independence.
