Maria Antónia Almeida Santos

Almeida Santos came relatively late to formal involvement in politics, not joining Socialist Youth, the youth arm of the PS, until she was 24. She served briefly as a deputy during the 8th legislature (1999–2002) and was then elected as deputy to the Assembly for the 10th legislature in 2005, as a representative of the Socialist Party. Until the 2011 election she represented Coimbra District, moving to represent Lisbon District in that year. From 2015 to 2019 she represented Guarda District before transferring to the Setúbal District for the 2019 Portuguese legislative election. In the January 2022 election, Almeida Santos was sixth on the PS list for Setúbal, with the party winning ten seats in the constituency and an overall majority nationwide.

In April 1986, when Mário Soares became president, she was asked to act as legal advisor to the President of the Republic. She worked directly with Maria Barroso, the wife of Soares, and the role gave her the opportunity to meet many other political personalities of the time. She stayed in this role until October 1995, working with a Lisbon law firm at the same time. From October 1995 to June 2001 she worked as a legal advisor in the office of the President of the Assembly of the Republic, when her father was in this position. From June 2001 to January 2005, she served as President of the Commission for the Avoidance of Drug Addiction in Lisbon, publishing two papers on drug addiction. In this role, she managed to get the use of cannabis for therapeutic purposes approved.
