Lula faces political challenges as Mercosur-EU deal signing approaches

President Lula faces growing disapproval in Brazil's Southeast region, while his son Flávio Bolsonaro leads voting intentions there. Lula will be the only Mercosur president absent from the signing of the trade agreement with the European Union, a move that reportedly caused surprise and anger in Argentina. Meanwhile, Brazil's government assesses that São Paulo Governor Tarcísio de Freitas could still enter the presidential race against Lula.
