Spain’s efforts to rally a progressive Ibero-American front have fallen short ahead of a high-level summit in Madrid, leaving Prime Minister Pedro Sánchez largely isolated among regional counterparts.
A Diminished Lineup in Madrid
The Ibero-American Summit, scheduled to take place in the Spanish capital between November 4 and 5, has secured the confirmed attendance of just 10 national leaders from the region, including host Spain.
elmundo.es reported that the turnout marks a notable drop from initial projections by Ibero-American Secretary General Andrés Allamand, who anticipated roughly 15 heads of state.

Left-Wing Allies Stay Home
Most notably, prominent left-wing figures such as Brazilian President Luiz Inácio Lula da Silva and Mexican President Claudia Sheinbaum have opted out of the gathering.
Their absences leave Prime Minister Sánchez without the key ideological allies he sought ahead of a tense domestic electoral precampaign, especially as he attempts to counter conservative political currents.
Following a historic electoral comeback in just three weeks after losing the first round, Lula defeated right-wing rival Jair Bolsonaro — a playbook very similar to what Sánchez is pursuing in these elections.
Similarly, Mexico’s Claudia Sheinbaum turned down the invitation. While the Mexican delegation was heavily involved in preparing the summit, Sheinbaum travels abroad very little.
Contrasting Regional Representation
Government sources cited by elmundo.es insist they remain satisfied with the overall representation, emphasizing that all 22 member nations will have delegates present. Alongside Spain, the leaders traveling to Madrid include the heads of state or government from Andorra, Argentina, Bolivia, Chile, Costa Rica, Guatemala, Honduras, Portugal, and the Dominican Republic. Colombia, Ecuador, and El Salvador will send their vice presidents, while the remaining nations will be represented by their respective foreign ministers.

diariodesantiago.es noted that this lineup stands in sharp contrast to the previous summit held in Cuenca, Ecuador. During the 2024 gathering—which Sánchez missed due to the devastating DANA storms in the Valencia region—only three heads of state participated: Spain’s King Felipe VI, Ecuadorian President Daniel Noboa, and then-Portuguese President Marcelo Rebelo de Sousa.
Oliver Blanco Replaces Delcy Rodríguez at Madrid Meetings
Diplomatic representation from Venezuela also changes. Delcy Rodríguez, who is sanctioned by the European Union, will not attend the Madrid meetings. Instead, Venezuela’s newly appointed foreign minister, Oliver Blanco, will take her place following his recent first meeting in Washington with U.S. Secretary of State Marco Rubio.
Despite the empty seats left by the region’s prominent socialdemocrats, Spanish officials maintain that the summit will fulfill its diplomatic purpose, having relaunched the Ibero-American community as a space for dialogue and cooperation.
