Dutch activist Eva Vlaardingerbroek, a prominent figure on Europe’s far-right speaking circuit, revealed on social media that her UK Electronic Travel Authorisation (ETA) had been revoked, with officials stating her presence was “not conducive to the public good.” The notification means she must now apply for a visa—and face a possible refusal—before entering the United Kingdom.
Vlaardingerbroek has promoted the “great replacement” conspiracy theory and addressed high-profile events organised by British nationalist Tommy Robinson. Her recent online attacks on Prime Minister Keir Starmer drew condemnation across the political spectrum and apparently triggered a security review by the Home Office’s Extremism Analysis Unit.
The decision underscores the discretionary power built into the ETA system, which will become mandatory for most visa-exempt travellers from 25 February 2026. Airlines and event organisers hosting controversial speakers will need to vet invitees earlier, as digital permissions can be cancelled at short notice, potentially leading to last-minute no-shows and reputational fallout.

Civil-liberties groups decried the move as a threat to free speech, while supporters argued it protects public order. Businesses arranging conferences should track ETA statuses proactively and consider contractual clauses covering speakers denied entry.
