The Federal Parliament is the bicameral parliament of Belgium. It consists of the Chamber of Representatives (Dutch: , , ) and the Senate (Dutch: , , ). It sits in the Palace of the Nation (, , ). The Chamber of Representatives is the primary legislative body; the Senate functions only as a meeting place of the federal communities and regions. The Constitution does not mention the Federal Parliament as such; it stipulates that the federal legislative power is exercised by the King and the Chamber of Representatives (and exceptionally the Senate), and defines when the United Chambers convene. Chamber of Representatives The Chamber of Representatives holds its plenary meetings in the Palace of the Nation, Brussels. Eligibility requirements for the Chamber are a minimum age of 21, citizenship, and residency in Belgium. The number of seats in the Chamber is constitutionally set at 150 elected from 11 electoral districts. The districts are divided along linguistic lines: 5 Flemish (87 seats), 5 Walloon (48 seats), and the bilingual district of Brussels (15 seats). The districts are the provinces and the Brussels Capital Region. Each district is given a number of seats proportional to its population (not the number of voters) ranging from 4 for Luxembourg to 24 for Antwerp. All districts have an electoral threshold of 5%, except for Brussels and Leuven. After the dissolution of the former Brussels-Halle-Vilvoorde district in 2013, which encompassed both the 19 bilingual municipalities from the Brussels-Capital region and some 35 Dutch-speaking municipalities in Flemish Brabant, incl. 7 with language facilities for French-speakers, voters in the 6 municipalities with language facilities surrounding Brussels have been given the right to vote in the Brussels district instead. The current composition was elected at the federal elections of 2019. Senate Since 2014, the Senate consists of 60 members. There are two categories of senators: co-opted senators and senators of community and regional parliaments. 50 senators are elected by and from the community and regional parliaments: 29 by the Flemish Parliament, 10 by the Parliament of the French Community, 8 by the Walloon Parliament, 2 by the French-language group of the Parliament of the Brussels-Capital Region, and 1 by the Parliament of the German-speaking Community. The 10 other senators are co-opted: elected by the 50 other senators. Eligibility requirements for the Senate are identical to those for the Chamber. Before 2014, the Senate consisted of 71 senators, only 21
