Peruvian Government

The politics of the Republic of Peru takes place in a framework of a presidential representative democratic republic, whereby the President of Peru is both head of state and head of government, and of a pluriform multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the Congress. The Judiciary is independent of the executive and the legislature.

The Republic of Peru is in a state of ongoing democratization. Led by President Pedro Pablo Kuczynski, the new government is expected to be transparent and accountable. Previously a rubberstamp body, Peru's unicameral Congress is emerging as a strong counterbalance to the once-dominant executive branch, with increased oversight and investigative powers. The executive branch and Congress are attempting to reform the judicial branch, antiquated and rife with corruption.

During the government of Fujimori the 1979 Constitution was changed after the Fujimori's Auto-coup where the president dissolved the Congress and established the new 1993 Constitution. One of the changes to the 1979 Constitution was the possibility of the president's immediate reelection (112 article) which made possible the reelection of Fujimori in the next years. After the Fujimori era and Fujimori's resign the transition government of Valentín Paniagua changed the article 112 and called new elections in 2001 where Alejandro Toledo was elected. After that Peru has had all democratically elected presidents.
