Short and plump with long dark hair, Isabel do Carmo, 35, is the daughter of an office worker in the factory town of Barreiro, an industrial suburb of Lisbon. She became a Communist at 15 and kept up with the party through years of medical school (an endocrinologist, she still sees patients twice a week). She broke with the Communists eight years ago to form the Brigades with her husband, Carlos Antunes (no kin to moderate Foreign Minister Ernesto de Melo Antunes). She clearly is the organization's boss. "In our party," says Carmo, "being a woman is no problem. After all, it is a revolutionary party."
