The full form of MPR is Majelis Permusyawaratan Rakyat.

The People’s Consultative Assembly of the Republic of Indonesia (Indonesian: Majelis Permusyawaratan Rakyat Republik Indonesia, MPR-RI) is the legislative branch in Indonesia’s political system. It is composed of the members of the People’s Representative Council (DPR) and the Regional Representative Council (DPD). Before 2004, and the amendments to the 1945 Constitution, the MPR was the highest governing body in Indonesia.

In accordance with Law No. 16/1960, the assembly was formed after the general election in 1971. It was decided at that time that the membership of the Assembly would be twice that of the House.

The 920 membership of MPR continued for the terms of 1977–1982 and 1982–1987. For the terms 1987–1992, 1992–1997, and 1997–1999 the MPR’s membership became 1000. One hundred members were appointed representing delegations from groups as addition to the faction delegates of Karya Pembangunan (FKP), Partai Demokrasi Indonesia (FPDI), Persatuan Pembangunan (FPP), and military (Fraksi ABRI, later renamed Fraksi TNI/POLRI). For the term of 1999–2004 the membership of MPR was 700 (462 civilians and 38 from military and police which formed the DPR, 135 from each of the 27 provinces which formed the Regional Delegations Faction (Fraksi Utusan Daerah), and 65 to form the Groups Delegations Faction (Fraksi Utusan Golongan). It was reduced to 688 in 2004 due to the removal of active military and police officers and the dissolution of the GDF, as well as the reassignment of Regional Delegations Faction to the newly-formed DPD and restructuring the senatorial seats at 128 from each of the 32 provinces. Due to addition of West Papua since the 2009 election, the number of DPD senators became 132. For the 2014–2019 term there are 560 DPR members and 132 senators, resulting in 692 members of the MPR.
