Manley, Michael Norman, 1924–97, prime minister of Jamaica (1972–80, 1989–92); son of Norman Manley. A leader of the socialist People's National party, he was first elected to parliament in 1967. Winning a landslide victory in 1972, he shifted Jamaican politics to the left, establishing close relations to Cuba, nationalizing industry, and denouncing U.S. imperialism. He was reelected in 1976, but in 1980 lost to conservative Edward Seaga. Manley was returned to power in 1989, this time leading a more moderate government and encouraging foreign investment. Following serious illness, he resigned in 1992.
