 Bloomberg -- A power struggle for Spains best-selling newspaper is coming to a head and Prime Minister Pedro Sanchez will be watching closely.Founded at the birth of Spanish democracy in the 1970s, El Pais has traditionally supported Sanchezs Socialists but has had a tense relationship with the new brand of left-wing politics pursued by the current premier.Sanchez has said publicly that the papers publisher, Prisa, was involved in the maneuvers that saw him ousted as party leader in 2016. El Paiss editorial page has attacked him repeatedly since his return to power for ignoring the advice of party elders who say his deals with Catalan separatists and the far-left group Podemos gift legitimacy to dangerous rivals.Now, it seems, Sanchez could catch a break. Prisas biggest shareholder wants to break up an old boys network club that is critical of the premier and still seen as pulling strings at El Pais.Joseph Oughourlian, founder of London-based hedge fund Amber Capital, is ready to vote to have Prisa Chairman Javier Monzon removed at a shareholders meeting on Monday, according to people familiar with his thinking speaking on condition of anonymity.Sanchezs closest advisers have been keeping tabs on the situation as the ballot approaches. Oughourlian has met with Sanchez since the prime minister took office -- both are 48, born the same month -- and hes developed a close relationship with at least two people in the premiers inner circle, according to a person who knows them both.A more sympathetic stance from the paper of national record could help a premier wrestling with the countrys worst recession in at least 70 years as he tries to maintain his balance atop a shaky coalition.Spain is not alone in having a paper of choice take political sides, and having an outsize influence in shaping the publics thinking on issues that can sway elections. Fox News, owned by billionaire Rupert Murdoch, is closely aligned with Donald Trump. In the U.K., Brexit was shaped by euroskeptic publications such as The Sun tabloid and the conservative The Telegraph.The same kind of ideological divisions are present in all the major publications in Germany, Italy and France. In Spain, however, its reached a boiling point.Oughourlian, who controls 29.8 of Prisa, has come to consider that Monzon is too close to Banco Santander SA and that he uses El Pais to pursue the banks political interests, the people said. While Monzon is an independent board member who was endorsed by Oughourlian and the rest of the board when he became non-executive chairman in January 2019, he was nominated by Santander and combines his role at Prisa with other non-executive posts as chairman of Santanders online unit Openbank and a board seat at the banks Spanish unit.Santanders financial influence at the publisher also goes way beyond its 4.1 stake. Its one of the highly leveraged companys main creditors and helped two other key shareholders with a combined 12.6 to finance their investments.Oughourlian and Sanchezs director of communication Miguel Angel Oliver declined to comment when contacted by Bloomberg, as did spokespeople for Prisa, Santander and Monzon.The Old GuardAt the heart of the dispute is a fight between the Spanish establishment and a new generation of leaders dealing with the legacy of the boom and bust years: a younger generation that missed out economically, a resurgence of the nativist far-right and question marks over the future of Catalonia.Old-school executives like Emilio Botin at Santander and Juan Luis Cebrian at Prisa amassed fortunes during the 1980s and 1990s under the Socialist administration of Felipe Gonzalez that opened up Spain after the Franco dictatorship. But that model, which involved close ties between government and business, came crashing down a decade ago in the financial crisis.The country today is divided and adrift. Tensions are on display in the streets, where people are angrily protesting the governments handling on the pandemic, and in company board rooms where executives worry what kind of concessions Sanchez will make to separatists and his anti-capitalist allies.Its also reflected in the feud between Sanchez and Prisa, which first blew up in 2016 after two consecutive elections produced no clear majority. Sanchezs original sin with the Socialist old guard was his refusal to step aside and let the center-right Peoples Party govern after his efforts failed to forge an unlikely coalition with centrist pro-business Ciudadanos and anti-establishment Podemos.Attack BackfiresWith Gonzalez helping to shape the newspapers coverage from his position on Prisas editorial advisory board and open attacks on Sanchez, El Pais rallied internal opposition to the party leader from its opinion pages. Sanchez resigned after losing the backing of the partys federal committee and, in a television interview at the time, accused Prisa of trying to undermine him.Cebrian, who was Prisa chairman at the time, said that blaming the press for a party decision was stupid and petty.Sanchez returned the following year to reclaim the party leadership and became prime minister in 2018.The mutual distrust remains.When Sanchez forged a second-term coalition with Podemos in January and promised to bring back protection for workers, many in the establishment feared their business interests were under threat. And the fact that the minority government also relied on votes from separatist parties stirred up old suspicions among more traditional socialists who identify more with Gonzalez and worry about the Catalan challenge to Spains territorial unity.Sanchez was asked about the rift with his predecessor in an interview published Sunday in La Vanguardia, Catalonias best-selling daily. He said, I listen to all the former prime ministers with full attention, but the social and political conditions in our country today are very different from what they were 40 years ago.Shake UpThen along comes Paris-born Oughourlian, who like the embattled prime minister is also an outsider to the Madrid elite and has argued that Prisa has been mismanaged for years. The investor has poured about 300 million euros 336 million into Prisa since 2015 and brushes aside reports that he is acting as a front man for Spanish investors who want to take control of the publisher.His fund pursues an activist strategy by engaging with executives and Oughourlian makes the case that El Pais should have a bigger profile throughout the Spanish-speaking world and textbook publisher Santillana, the companys largest source of revenue, should deliver more money to investors.There are already signs that change is coming. Telefonica SA Chairman Jose Maria Alvarez-Pallete toyed with the idea of naming an ally of Sanchez and Oughourlian to the Prisa board, according to two people familiar with his thinking. That would have been a major reversal for the companys second-biggest shareholder. Pallete has been trying to keep Telefonica out of politics. A spokesman for Telefonica declined to comment. Oughourlian has already dealt with one of Sanchezs enemies when he led a push to force out Monzons predecessor, Cebrian, in 2017. But hes still not satisfied with the way the company is being run.On Monday hell have another chance to put that right. The results will be announced around lunchtime.For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.2020 Bloomberg L.P.
