Left-wing groups, affiliated directly or indirectly with the Communist Party of the Philippines, played a prominent role in anti-regime demonstrations after August 1983. While the New People's Army was spreading in rural areas, the communists, through the National Democratic Front, gained influence, if not control, over some labor unions, student groups, and other urbanbased organizations. Leftists demanding radical political change established the New Nationalist Alliance (Bagong Alyansang Makabayan--BAYAN), in the early 1980s, but their political influence suffered considerably from their decision to boycott the presidential election of February 1986.
