The Polish lawmaker joins former Republican Party candidate Valentina Gomez, US political strategist Joey Mannarino, Spanish influencer Ada Lluch and Dutch activist Eva Vlaardingerbroek in being prohibited from setting foot in Britain.

All of them have had their electronic travel authorisations either cancelled or refused by the Home Office, with Shabana Mahmood deeming their presence “not conducive to the public good”.

Mr Tarczynski – who has long called for Britain and other Western nations to “be like Poland” in approaching mass migration – launched a scathing attack on the Labour Government after his visa was cancelled.

He wrote on social media: “This is what communism looks like in the 21st century. I have just been denied entry to the UK in order to speak at the largest patriotic event in Europe.

“Starmer will be sued by me. Not the Government, not the Home Office but Starmer personally. Once you lose the next election, communist, we’ll meet in court!”

The MEP added: “This communist cannot silence millions, nor can he take away their right to vote! UNITE THE KINGDOM!”

On Monday, the PM blasted this weekend’s planned rally, declaring it was “designed to confront and intimidate this diverse city and this diverse country”.

He added: “That is why this Government will block far-right agitators from travelling into Britain for that event.

“Because we will not allow people to come to the UK, threaten our communities, and spread hate on our streets.”

The sweeping bans were celebrated by Roshan Salih, editor of Muslim outlet 5Pillars, who told Robinson: “We have absolutely decimated your speakers list for your march on Saturday.”

“Please be aware that Muslims got this done,” he added.

Ms Gomez – who spoke at last year’s Unite the Kingdom rally – had her visa to enter Britain terminated last month, despite having already secured clearance.

The Colombian-born influencer has since threatened to defy the Home Secretary and travel by small boat, daring the Government to stop her while suggesting Donald Trump’s White House would intervene if the authorities try to arrest her.

Meanwhile, Ms Vlaardingerbroek – a former member of the Dutch Forum for Democracy political party – had her visa revoked by the Home Office in January.

The decision sparked a row with the Trump administration – which has frequently hit out at European leaders over their alleged suppression of free speech.

Like Ms Gomez, the Dutch activist also spoke at last year’s Unite the Kingdom rally, which is believed to have been attended by up to 150,000 people.

She used her platform in September to call for the “remigration” of immigrants and to talk about the “replacement of our people”.

Robinson has described Saturday’s rally as a “beautiful celebration of British identity”, urging supporters on social media to be on their “best behaviour”.

It falls on the same day as the FA Cup final between Chelsea and Manchester City at Wembley and a planned pro-Palestine demonstration to mark “Nakba Day”.

Met Commissioner Sir Mark Rowley previously said he was “concerned” about the scale of the protests, with his force vowing to impose strict conditions on on routes and gathering points to avoid serious disorder.

Meanwhile, a spokesman for the Prime Minister said: “Those who threaten our communities and spread racism have no place on the streets of the UK.

“Where individuals pose a threat or seek to spread extremism the Government won’t hesitate to deny entry.”
