Delga has been a member of the Socialist Party since 2004.
Member of the National Assembly, 2012–2017 From 2012 until 2017, Delga was a member of the
National Assembly, where she served on the Finance Committee (2012–2014) and the Defence Committee (2015–2017). In 2014, Delga briefly served as Secretary of State for Trade, Crafts, Consumer and Social Economy and Solidarity under
Minister of Finance and Public Accounts Michel Sapin in the
government of Prime Minister
Manuel Valls; she replaced
Valérie Fourneyron who had resigned for health reasons. In June 2015, she left the government to launch her campaign for regional elections; she was replaced by
Martine Pinville.
President of Occitanie, 2016–present Ahead of the Socialist Party's
2017 primaries, Delga publicly endorsed Manuel Valls as the party's candidate for the
presidential election later that year. Since 2017, she has been part of the party's leadership. Delga was re-elected in the
2021 French regional elections. Shortly after, she was also elected as president of Régions de France, a group representing the
regions of France; it was the first time since 2016 that the association was led by a left-wing personality, and for the first time by a woman. Ahead of the
2022 presidential election, Delga endorsed
Anne Hidalgo as the Socialist Party's candidate. In 2023, she publicly endorsed
Nicolas Mayer-Rossignol as candidate to challenge
Olivier Faure for the party's leadership. During the 2025 party leadership election, she did the same, and threatened to leave the PS if Faure was elected party leader again. Shortly after Faure was elected again, Delga ultimately announced she would not quit the party after all, contrary to her earlier threat. == Political positions ==
