The United Republic of Tanzania is a multi-party republic consisting of the mainland region and the semiautonomous Zanzibar archipelago, whose main islands are Unguja and Pemba. The union is headed by a president, who is also the head of government. Its unicameral legislative body is the National Assembly (parliament). Zanzibar, although part of the union, has its own government with a president, court system, and legislature, and exercises considerable autonomy. Tanzania held its fourth multi-party general elections in 2010 in which voters on mainland Tanzania and Zanzibar elected a union president (Jakaya Kikwete) and their respective representatives in the union legislature. The Zanzibari electorate chose Ali Mohamed Shein as president of Zanzibar. The union and Zanzibari elections were judged to be largely free and fair. Union security forces reported to civilian authorities, but there were instances in which elements of the security forces acted independently of civilian control. Security forces at times committed human rights abuses. The three most widespread and systemic human rights problems in the country were excessive use of force by security forces resulting in deaths and injuries, gender-based violence including female genital mutilation/cutting (FGM/C), and lack of access to justice as well as a related continuation of mob violence. Other human rights problems included harsh and life-threatening prison conditions, lengthy pretrial detention, some restrictions on religious freedom, restrictions on the movement of refugees, official corruption, restrictions on political expression, child abuse, and discrimination based on sexual orientation, and societal violence against persons with albinism. Trafficking in persons, both internal and international, as well as child labor were also problems.
