The PS is tasked with finding a new leader who can rebuild its relationship with the public and address the rise of far-right sentiments in the political landscape.

Pedro Nuno Santos has resigned as secretary-general of the Socialist Party (PS) following a historic electoral defeat, marking the party's worst performance in 38 years.

The PS is now focused on reviewing the political landscape after the May 18 elections and preparing for upcoming local elections.

Sources indicate that José Luís Carneiro is being approached by party members and civil society as a potential leader to guide the party through this transitional phase.

Prominent voices within the party, including Luísa Salgueiro and Francisco Assis, advocate for delaying the leadership election until after local elections to allow for reflection and recovery.

Carlos César, the current president of the PS, will assume interim leadership until a new leader is elected, with a party congress scheduled for spring 2026 to finalize the leadership selection.

The party's immediate priorities include winning local elections and preparing for the presidential election, which are critical for regaining its footing in Portuguese politics.

Mariana Vieira da Silva has expressed her willingness to contribute to party unity and leadership discussions, highlighting the need for deep reflection on strategies after the recent electoral results.

The PS must differentiate its message from parties on its left and maintain its identity as an inclusive party that resonates with various political ideologies.

Candidates for leadership are encouraged to adopt a more inclusive approach, emphasizing social justice and community engagement to appeal to a broader electorate.

The National Commission is expected to propose that the election for the new secretary-general occurs by late June or early July 2025, ensuring the future leader has legitimacy.

Pedro Nuno Santos expressed gratitude to supporters and indicated a commitment to the party's values, stating, 'Only those who give up fighting are defeated,' as he steps down.
