. According to the Constitution of Portugal, the parliament "is the representative assembly of all Portuguese citizens". The constitution names the assembly as one of the country's organs of supreme authority. It meets in São Bento Palace, the historical site of an old Benedictine monastery. The palace has been the seat of the Portuguese parliaments since 1834 ( Cortes until 1910, Congress from 1911 to 1926 and National Assembly from 1933 to 1974).

. The constitution requires the assembly to quickly review and approve an incoming government's program. Parliamentary rules allow the assembly to call for committees of inquiry to examine the government's actions. Political opposition represented in the assembly has the power to review the cabinet's actions, even though it is unlikely that the actions can be reversed. Party groups can also call for interpellations that require debates about specific government policies.

Structure

The assembly has 230 MPs. It originally consisted of 250 MPs, but the constitutional reforms of 1989 reduced its number to between 180 and 230. Members are elected by popular vote for legislative terms of four years from the country's twenty-two constituencies. There are eighteen in mainland Portugal corresponding to each

, which elects 48 representatives, to as small as Portalegre, which elects just two. For the 2025 legislative elections, the MPs were distributed by constituencies as follows: According to the constitution, members of the assembly represent the entire country, not the constituency from which they are elected. This directive has been reinforced in practice by the strong role of political parties in regard to members of the assembly. Party leadership, for example, determines in which areas candidates are to run for office, thus often weakening members' ties to their constituencies. Moreover, members of the assembly are expected to vote with their party and to work within parliamentary groups based on party membership. Party discipline is strong, and insubordinate members can be coerced through a variety of means. A further obstacle to members' independence is that their bills first have to be submitted to the parliamentary groups, and it is these groups' leaders who set the assembly's agenda. The President of the Assembly of the Republic is the second hierarchical figure in the Portuguese state, after the President of the Portuguese Republic, and is elected by secret vote of the members of parliament. The President of the Assembly is aided by four vice presidents, nominated by the other parties represented in the parliament, and is usually the speaker. When they are not present, one of the vice presidents takes the role of speaker. When the President of the Republic is, for any reason, unable to perform the job, the President of the Assembly of the Republic becomes the substitute.
