About the election Short description of the context and results of the election.
The 2018 elections returned a fragmented Congress, with 30 parties winning seats in the 513-member Chamber of Deputies and 20 parties sharing 54 seats up for renewal in the 81-member Senate. The Workers' Party (PT) remained the largest party in the Chamber of Deputies, winning 56 seats, down from 70 in 2014. The Social Liberal Party (PSL), which held only one seat in the outgoing legislature, became the second largest party, winning 52. The number of women increased from 51 to 77 in the Chamber of Deputies and from 11 to 12 in the Senate. A woman of indigenous descent was elected to the Chamber of Deputies, becoming the first indigenous woman to enter the Brazilian Congress. No candidate secured a majority in the first round of the presidential elections held in parallel with the parliamentary elections. In the run-off elections held on 28 October, former army captain Jair Bolsonaro (PSL) defeated Mr. Fernando Haddad (PT). The PSL pledged to fight crime and corruption while the PT promised to reverse austerity measures and boost spending to drag the country out of the recession. On 1 January 2019, Mr. Bolsonaro assumed the presidency. His government comprised his PSL, the Democrats (DEM), the Brazilian Democratic Movement (MDB), the Brazilian Republican Party (PRB) and Novo. The 2018 elections were held amid political turmoil marked by numerous corruption scandals involving prominent political figures from various parties, including former heads of State and members of parliament.
