Polish MEP Dominik Tarczyński has vowed to sue U.K. Prime Minister Keir Starmer personally after the Home Office cancelled his permission to travel to Britain ahead of a major patriotic rally in London on Saturday.
Tarczyński, a conservative Polish politician and outspoken critic of mass migration, published an image on X showing an official Home Office message informing him that his U.K. Electronic Travel Authorisation (ETA) had been cancelled ahead of the event.
The notice stated, “Your UK ETA has been cancelled from 12 May 2026. This means you cannot travel to the UK without a visa.”
It added that the decision had been taken because his presence in the country was “not considered to be conducive to the public good,” and said he had no right of appeal.
Tarczyński responded, writing on social media, “This is what communism looks like in the 21st Century. I have just been denied entry to the U.K. in order to speak at the largest patriotic event in Europe.”

The Polish MEP had been due to speak at the “Unite the Kingdom, Unite the West” rally organized by Tommy Robinson on May 16.
He is the latest conservative figure to be barred from entering Britain before the event. Belgian politician Filip Dewinter, a member of the Flemish Parliament, also said he had been blocked after receiving a similar Home Office message stating that his presence would not be “conducive to the public good.”
Other figures reportedly barred from entering Britain include U.S. commentator Joey Mannarino, MAGA influencer Valentina Gomez, and Spanish political commentator Ada Lluch. The Guardian reported that seven foreign speakers linked to the Robinson rally had been stopped from entering the country.
The row comes after Starmer used a speech on Monday to promise that “far-right agitators” would be kept out of Britain ahead of the rally. The prime minister claimed the event was designed to “confront and intimidate” the country’s diverse communities.
The intervention also came as Starmer faced the gravest crisis of his premiership, with more than 70 Labour MPs and senior figures calling for him to resign after disastrous local election results and a poorly received attempt to reset his leadership. Several government ministers also resigned as pressure mounted inside the parliamentary party.
The decision to block foreign conservative speakers from entering Britain is also likely to intensify criticism of Starmer’s approach to free speech.
His government has previously defended Britain’s free speech record, including during the latest visit of U.S. President Donald Trump, who had expressed concern about the country’s direction after several high-profile cases involving citizens being jailed for social media posts.
The Home Office has repeatedly relied on the same “not conducive to the public good” justification when barring right-wing commentators and politicians from entering the country, including Dutch conservative commentator Eva Vlaardingerbroek earlier this year.
