Paraguay is a multiparty, constitutional republic. In 2008 Fernando Lugo of the Patriotic Alliance for Change won the presidency in elections that were generally free and fair. Security forces reported to civilian authorities. The principal human rights problems were killings by police or government officials; harsh, occasionally life-threatening conditions in prisons; and political interference, corruption, and inefficiency in the judiciary. Discrimination and violence against women; indigenous persons; persons with disabilities; and lesbian, gay, bisexual, and transgender (LGBT) persons continued, as did trafficking in persons. Exploitation of child labor and violations of worker rights also remained serious problems. There was impunity for officials who committed abuses in the security forces and elsewhere in government.
