The claims coincide with suggestions that Bannon’s pan-European populist project, the Movement, has stalled. Meanwhile, Salvini has announced that he wants to bring the far right from across Europe into an alliance. Last Monday in Milan, he unveiled his “vision of Europe for the next 50 years”, billing it as the launch of a new rightwing coalition for the European parliamentary elections on 23 May. Salvini unveiled his alliance only days after meeting Bannon in Rome in March. This led some to believe that Bannon has handpicked Salvini as the informal leader of Eurosceptic, populist forces in Europe.
Bannon, in an interview with NBC and SourceMaterial to be broadcast at 9pm eastern time in the US on Sundayon , also takes issue with the pope’s warnings over resurgent populist movements. “You can go around Europe and it’s [populism] catching fire and the pope is just dead wrong,” said Bannon.
The slogan refers to a Vatican version of the “birther” campaign waged by Trump against Barack Obama, claiming that Francis’s papacy is illegitimate and that his ultra-conservative predecessor Benedict XVI is in fact the true pontiff.
The League source also alleged that Salvini would have attacked the pope harder but was restrained by his own party, predominantly by Giancarlo Giorgetti, the deputy federal secretary of Lega Nord who is close to senior figures in the Vatican.
“[After the Bannon meeting] Salvini moved very tough and said: ‘We have to attack the Vatican, but the other guy said wait.’ Salvini thinks by himself and acts by himself ... so he started to act [for example, by appearing with the ‘Benedict is my Pope’ T-shirt],” said the source.
Bannon has steadily been building opposition to Francis through his Dignitatis Humanae Institute, based in a 13th-century mountaintop monastery not far from Rome.
In January 2017, Bannon became a patron of the institute, whose honorary president is Cardinal Raymond Burke, an ultra-conservative who believes organised networks of homosexuals are spreading a “gay agenda” in the Vatican.
The institute’s chairman is former Italian MP Luca Volontè, on trial for corruption for accepting bribes from Azerbaijan . He has denied all charges.
Among the institute’s trustees is one of the pope’s most outspoken critics, Austin Ruse, a former contributor to rightwing news website Breitbart. Ruse runs C-FAM, an anti-abortion group whose founder was prone to antisemitic rants about population control and which has been termed a hate group by human rights campaigners. Like Volontè, Ruse is an official of the World Congress of Families, a gathering of far-right, anti-gay Christian groups backed by Konstantin Malofeev, a Russian oligarch close to Vladimir Putin.
Other trustees include Ben Harris-Quinney, chairman of the Conservative thinktank the Bow Group, who met Bannon in London last summer, alongside Raheem Kassam, the former UK editor of Breitbart. Bannon was a founding member of Breitbart’s board.
Bannon was invited by the Observer to respond but at the time of publication had not yet replied.
