The Socialist Party (PS) accuses Lisbon Mayor Carlos Moedas of illegally keeping the head of the General Secretariat, Alberto Laplaine Guimarães, in office. Guimarães was arrested as part of 'Operation Lumen' due to suspected irregularities in Christmas lighting contracts. The PS argues that his tenure exceeded the legal ten-year limit and that his position should have been subject to a new public tender. Additionally, the PS criticizes Moedas for a lack of political accountability regarding the scandal and questions the transparency of the municipal administration.
