A year before a general election in Spain, which polls suggest he will struggle to win, Sánchez is the only candidate to head the Socialist International (SI) — an umbrella group of 132 centre-left parties from around the world.

The telegenic 50-year-old will take over the reins of the SI, which is gathering in Madrid this weekend, from former Greek prime minister George Papandreou.

“While symbolic… this post could be a way (for Sánchez) to regain credit among voters by presenting himself as influential on the world stage,” said Pablo Simón, political science professor at the Carlos III University.

“But it also could be that he plans on capitalising on this network of international contacts” which the post offers to “play a prominent role later” in a top global body, he added.

Former Portuguese prime minister Antonio Guterres led the International Socialist before he went on to head the United Nations refugee agency in 2005 and then become UN secretary general in 2017.

“All prime ministers who love foreign affairs have a tendency to look for an international post to secure a post-governmental career,” said Teneo Intelligence analyst Antonio Barroso.

‘More weight’

Sánchez has made international affairs a priority since he came to power in June 2018, in contrast to his conservative predecessor Mariano Rajoy, and has sought to boost Spain’s influence in the European Union.

Within days of taking office, Sánchez made international headlines by agreeing to take in migrants from the Aquarius rescue ship who were rejected by other European nations.

The first modern Spanish premier to speak English fluently, Sánchez served as chief of staff to the UN high representative to Bosnia during the Kosovo conflict.

He has fostered good relations with France and Germany, which has made Spain “one of the engines of European politics”, said Simon, citing as an example Madrid’s lead in talks over the energy crisis sparked by the war in Ukraine.

Sánchez successfully lobbied to have his foreign minister, Josep Borrell, appointed as European Union foreign policy chief in 2019.

“Spain has much more weight in the European Union debate than 10 years ago,” said Barroso, adding the premier had “boosted Spain’s credibility” with its “European partners”.

Beyond the EU, Sánchez hosted a crucial NATO summit in Madrid in June, just four months after Russia’s invasion of Ukraine, and has “reconnected” with Latin America, which has shifted to the left in recent years, said Simon,

Sánchez visited four Latin American countries in August 2018, his first official trip outside Europe, in what was seen as an effort to underscore the region as a priority of his foreign policy.

With Biden and Macron

During the recent G20 summit in Indonesia, Sánchez posted a photo of himself meeting German Chancellor Olaf Scholz, French President Emmanuel Macron, British Prime Minister Rishi Sunak and US President Joe Biden.

Seen as an attempt to burnish his credentials on international affairs, the photo was much mocked on social media.

But Ignacio Molina, a senior analyst at the Elcano Royal Institute think tank, said he believes Sánchez’s priority is to remain Spanish prime minister after the general election, which is expected at the end of 2023.

The speculation about a possible senior role for Sánchez at a global body comes from Spain’s opposition parties, which have “spread the idea that he uses international meetings to prepare his future in case of an electoral defeat next year”, Molina said.

“I don’t think he’s deliberately developing an international network for personal reasons. It’s more because he’s at ease in European politics, where he faces less opposition.”
