The highest representative body at national level is the People's Consultative Assembly (MPR). Its main functions are supporting and amending the constitution, inaugurating the president, and formalising broad outlines of state policy. It has the power to impeach the president. The MPR comprises two houses; the People's Representative Council (DPR), with 560 members, and the Regional Representative Council (DPD), with 132 members. The DPR passes legislation and monitors the executive branch; party-aligned members are elected for five-year terms by proportional representation.[64] Reforms since 1998 have markedly increased the DPR's role in national governance.The DPD is a new chamber for matters of regional management.
