The Congress of the Republic of Peru () is the unicameral body that assumes legislative power in Peru. Congress' composition is established by Chapter I of Title IV of the Constitution of Peru. Congress is composed of representatives who sit in congressional districts allocated to each region, as well as two special districts, Lima Province and Peruvian citizens living abroad, on a basis of population as measured by the Peruvian Census in multi-member districts. The number of voting representatives is fixed by the Constitution at 130. Pursuant to the 2017 Census, the largest delegation is that of Lima Province, with 36 representatives. Due to broadly interpreted impeachment wording in the 1993 Constitution of Peru, the Congress can impeach the President of Peru without cause, effectively making the legislature more powerful than the executive branch. Congress is charged with the responsibility to pass laws and legislative resolutions, as well as to interpret, amend, or repeal existing laws. Congress also ratifies international treaties, approves the national budget, and authorizes loans on behalf of the country. It may also override presidential observations to bills by a vote of more than half the legal number of congressmen. It can also remove government official including the President, consent to the entry of foreign troops into the national territory, and authorize the President to leave the country. Congress meets at the Legislative Palace in Lima. The presiding officer is the President of Congress, who is elected by the members thereof (and is therefore traditionally the leader of the controlling party). The President and three vice-presidents are chosen by the controlling governing coalition. History The first Peruvian Congress was installed in 1822 as the Constitutional Congress led by Francisco Xavier de Luna Pizarro. In 1829, the government installed a bicameral Congress, made up by a Senate and a Chamber of Deputies. This system was interrupted by a number of times by Constitutional Congresses that promulgated new Constitutions that lasted for a couple of years. The Deputies reunited in the Legislative Palace and the Senators went to the former Peruvian Inquisition of Lima until 1930, when Augusto B. Leguía was overthrown by Luis Miguel Sánchez Cerro. He installed a Constitutional Congress (1931–1933) that promulgated the Constitution of 1933. By order of the president, the Peruvian Aprista Party members that were in Congress were arrested for their revolutionary doctrines against the government. When Sánchez Cerro was assassinated in 1933
