Alex Armstrong has launched a blistering attack on Sir Keir Starmer after the Prime Minister vowed to block “far-right agitators” from entering Britain ahead of this weekend’s Unite the Kingdom rally in London.

The GB News presenter accused the Labour leader of targeting political opponents while failing to crack down on other extremist demonstrations in the capital.

Posting on X, Alex wrote: “Starmer attacks the upcoming Unite the Kingdom rally, hailing how he’s banned some social media critics from coming to Britain.

“Meanwhile, hate marchers have been parading around London for years under his watch, with ZERO intervention by the PM until an alleged terror attack against Jews.

“You cannot make it up. This was a speech for the far left of his party, not for the country.”

Alex’s comments came after Sir Keir used a major speech on Monday to condemn the upcoming demonstration, which is being organised by hard-right activist Tommy Robinson.

The Prime Minister described the march as an event “designed to confront and intimidate” Britain’s diversity, while promising to stop overseas activists travelling to the UK to attend.

Sir Keir said: “That is why this Labour Government will block far-right agitators from travelling to Britain for that event because we will not allow people to come to the UK and spread hate on our streets.”

Home Secretary Shabana Mahmood has reportedly used Home Office powers to revoke entry permissions for at least seven individuals ahead of the protest.

Among those who are said to be blocked are US-based commentator Valentina Gomez and right-wing commentator Joey Mannarino.

The Unite the Kingdom rally is expected to attract more than 100,000 people to central London on Saturday, according to police estimates.

A separate pro-Palestine march marking Nakba Day is also due to take place on the same day, prompting the Metropolitan Police to prepare a major security operation.

Alex’s post quickly drew strong reactions online, with many users criticising the Government’s stance.

One user replied on X: “Dangerous stuff indeed @Alexarmstrong. This is entirely unacceptable.”

Another added: “Keir Starmer’s decision to block activists from entering the UK to attend the Unite The Kingdom rally on May 16 is a blatant attack on free speech and the democratic right to peaceful assembly.”

“What about all the Muslim hate preachers he allows? They all need to be shut down once and for all,” penned a third.

One commenter claimed: “We have a government that is anti-British, anti-Christian and hates free speech.”

Another said: “Won’t he just be adding numbers to the march? He really is a bit silly.”

A further user wrote: “We have had free speech in Britain for a very long time and long may it continue… well as long as it’s approved by ‘my government’ and it’s left leaning! Absolutely tone deaf dictator!”

The previous Unite the Kingdom march in September 2025 drew between 110,000 and 150,000 demonstrators, according to the Metropolitan Police.

This year’s rally will take place on the same day as the FA Cup Final at Wembley, with Scotland Yard expected to impose strict Public Order Act conditions on both demonstrations.
