The politics of Bolivia takes place in a framework of a presidential representative democratic republic, whereby the president is head of state, head of government and head of a Diversity multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the two chambers of parliament. Both the Judiciary and the electoral branch are independent of the executive and the legislature. After the 2014 election, 53.1% of the seats in national parliament were held by women, a higher proportion of women than that of the population.
