MILAN — Stephen K. Bannon leaned back in an armchair opposite a copy of a painting by an Italian old master and explained his modest efforts to build a vast network of European populists to demolish the Continent’s political establishment.
“All I’m trying to be,” he said, “is the infrastructure, globally, for the global populist movement.”
Just that.
Only months ago, Mr. Bannon was forced out of the White House and Breitbart News, the alt-right news empire he helped make into a political force, for the sharp criticisms of President Trump’s children attributed to him in a book. “He’s lost his mind,” Mr. Trump said at the time.
But now Mr. Bannon, the architect of Mr. Trump’s populist campaign message and the president’s former chief strategist, has returned with an international mission.
On Saturday, he is set to headline the annual conference of France’s far-right National Front in the northern city of Lille, where he will be introduced by its leader, Marine Le Pen. People with knowledge of Mr. Bannon’s itinerary suggested that he might meet later in the weekend with the Hungarian prime minister, Viktor Orban, but Mr. Bannon declined to say whether or not he would, only saying that he admired Mr. Orban as a “hero” and “the most significant guy on the scene right now.”
