The highest representative body at the national level is the People's Consultative Assembly (''Majelis Permusyawaratan Rakyat'', MPR). Its main functions are supporting and amending the constitution, inaugurating and impeaching the president, and formalising broad outlines of state policy. The MPR comprises two houses; the People's Representative Council (''Dewan Perwakilan Rakyat'', DPR), with 575 members, and the Regional Representative Council (''Dewan Perwakilan Daerah'', DPD), with 136. The DPR passes legislation and monitors the executive branch. Reforms since 1998 have markedly increased its role in national governance, while the DPD is a new chamber for matters of regional management.
