The People's United Democratic Movement (PUDEMO; Swazi: Insika Yenkhululeko Yemaswati) is the largest opposition party in Eswatini. It is a democratic socialist party. Formed in 1983 at the University of Eswatini, it is led by Mlungisi Makhanya. The Swazi government has been monitoring PUDEMO closely since it launched the Ulibambe Lingashoni ("Don't Let the Sun Set") campaign, which aims for a "total liberation" of Eswatini, and has recently cracked down heavily on even small manifestations of support for PUDEMO, such as the death in custody of PUDEMO member Sipho Jele, who was arrested for wearing a PUDEMO t-shirt in May 2010.
