Eurico Jorge Nogueira Leite Brilhante Dias (born 15 March 1972) is a Portuguese politician who served as the leader of the Socialist Party's parliamentary group in the Assembly of the Republic from 2022 to 2024.[1]
Brilhante Dias was a supporter of António José Seguro during the 2014 prime ministerial primaries. After António Costa defeated Seguro, Brilhante Dias was firstly elected to the Assembly of the Republic in Castelo Branco.[2] He supported Maria de Belém Roseira's candidacy in the 2016 presidential election, criticizing the Socialist Party for not supporting a candidate in that election.
In 2017, following Jorge Oliveira's resignation as Secretary of State for Internationalization, Brilhante Dias was appointed by António Costa for that position.[3]
After the 2022 election, Brilhante Dias was chosen for the position of leader of the Socialist parliamentary group, succeeding Ana Catarina Mendes who became the Minister of Parliamentary Affairs.[4]
Brilhante Dias supported José Luís Carneiro during the 2023 leadership election, that was ultimately won by Pedro Nuno Santos.[5] He was later chosen as the main candidate of the Socialist Party for Leiria in the 2024 election.[6]
