Argentina - October 2025
Mid-term legislative elections result in victory for the ruling party
On 26 October, Argentina held legislative elections to renew half of the members of the Chamber of Deputies (127 seats) and one-third of the members of the Senate (24 seats). Two main political coalitions won the majority of votes across the country: the incumbent La Libertad Avanza (LLA) and the opposition Fuerza Patria/Peronismo (FP) alliance. In the Chamber of Deputies, LLA received 41.5 per cent of the vote, followed by FP with 34.9 per cent. In the Senate, LLA also led with 42.0 per cent, while FP followed with 36.9 per cent. Despite voting being mandatory, voter turnout was 67.9 per cent, down from 71.5 per cent in the 2021 mid-term legislative elections. At the time of writing, data on women elected to Congress was not available. This election marked the first time the country voted using a Single Paper Ballot (SPB), replacing the previous party ballot system.
