The former chief strategist to Donald Trump has spent months trying to recruit European parties to his Brussels-based group, the Movement, which he promised would operate as kind of a political consultancy for like-minded parties campaigning in the bloc-wide vote in May 2019.

But the Guardian has established that Bannon would be barred or prevented from doing any meaningful work in nine of the 13 countries in which he is seeking to campaign, according to national electoral bodies and relevant ministries. Confronted with the findings, Bannon acknowledged he was taking legal advice on the matter.

“I’m not totally disagreeing with you,” he told the Guardian in Paris. “I think there is more flexibility in some areas. But there’s no chance we would ever break the law.”

Further disclosures about Bannon’s operation to foment a Trump-style populist insurgency in Europe are revealed in a Guardian documentary.
