Peru is a presidential representative democratic republic with a multi-party system.

Under the current constitution, the President is the head of state and government; he or she is elected for five years and can only seek re-election after standing down for at least one full term. The President designates the Prime Minister and, with his advice, the rest of the Council of Ministers.

Congress is unicameral with 130 members elected for a five-year term. Bills may be proposed by either the executive or the legislative branch; they become law after being passed by Congress and promulgated by the President.

The judiciary is nominally independent, though political intervention into judicial matters has been common throughout history and arguably continues today.

The Peruvian government is directly elected, and voting is compulsory for all citizens aged 18 to 70. General elections held in 2011 ended in a second-round victory for presidential candidate Ollanta Humala of the Gana Perú alliance (51.4% of valid votes) over Keiko Fujimori of Fuerza 2011 (48.5%).

Congress is currently composed of Gana Perú (47 seats), Fuerza 2011 (37 seats), Alianza Parlamentaria (20 seats), Alianza por el Gran Cambio (12 seats), Solidaridad Nacional (8 seats) and Concertación Parlamentaria (6 seats).

Peru is an active member of several regional blocs and one of the founders of the Andean Community of Nations. It is also a participant in international organizations such as the Organization of American States and the United Nations.

The Peruvian military is composed of an army, a navy and an air force; its primary mission is to safeguard the independence, sovereignty and territorial integrity of the country. The armed forces are subordinate to the Ministry of Defense and to the President as Commander-in-Chief. Conscription was abolished in 1999 and replaced by voluntary military service.
