Wikipedia places it at the centre to centre-right and lists four Brazilian presidents among its members. Baleia Rossi leads it. It holds 36 of 513 Chamber of Deputies seats and is named in the 2026 Chamber of Deputies election.

History

The MDB was founded on 4 December 1965 as the official opposition under the dictatorship's two-party system. After the return to multiparty politics it was reorganised on 15 January 1980 as the PMDB, and on 19 December 2017 it took back the name MDB, to distance itself from associations with corruption. It has produced four presidents of Brazil: Tancredo Neves, José Sarney, Itamar Franco and Michel Temer. Baleia Rossi is its president and Jorge Caruso its secretary-general. It holds 36 of the 513 seats in the Chamber of Deputies and 8 of the 81 Senate seats, and claims over two million members.

Positions

Wikipedia describes the MDB as a big-tent party without a cohesive programme, identifying with economic liberalism and Christian democracy, ranging from the centre to the centre-right, whereas historically it ran from the centre to the centre-left. Critics, Wikipedia notes, call it a physiological party that trades its support for government posts and resources.
