Muslim British Man Known as J4 Loses His Citizenship After MI5 Finds Shocking WhatsApp Messages on His Phones

A former delivery driver who held British citizenship has lost his legal battle to get his citizenship back after the UK’s security service, MI5, identified him as a possible terrorist threat. The decision came after investigators discovered WhatsApp messages in which he appeared to discuss attacking a controversial Danish politician who had planned to burn a copy of the Koran in Britain.

The man, whose real name has not been made public, is known only as J4 because of a court order protecting his identity. His case has raised questions about national security, freedom of speech and the government’s power to remove British citizenship from people considered a danger to the country.

According to evidence presented to the Special Immigration Appeals Commission, the incident began in March 2023 when Rasmus Paludan, a far-right Danish politician known for publicly burning copies of the Koran, announced plans to visit Wakefield in West Yorkshire.

Paludan’s planned visit attracted attention because of his history of organising demonstrations against Islam. His actions had previously caused anger and violent protests in several European countries.

As news of his possible visit spread, J4 became involved in a WhatsApp conversation about the politician and his plans.

During the exchange, J4 shared an Instagram link relating to Paludan’s proposed demonstration. He also suggested that he might travel to Wakefield to attend the event.

However, it was the language he used in the conversation that later attracted the attention of British security officials.

According to the evidence heard by the commission, J4 said he was “gonna try” to attend the demonstration. He then made a statement suggesting that he did not intend to take part in a peaceful protest.

Instead, he said he would “not protest” but would “attack that kuffar”, using a derogatory expression sometimes directed at non-Muslims.

Security officials considered the messages particularly concerning because they appeared to suggest that J4 was prepared to use violence against the Danish politician.

Following the discovery of the messages, J4 was arrested by police while the authorities investigated the circumstances surrounding his comments.

He was later released on bail, and the Crown Prosecution Service eventually decided that no further action would be taken against him. His bail conditions were also removed.

However, the decision not to prosecute him did not bring the matter to an end.

Although the criminal investigation did not result in charges, MI5 continued to consider whether J4 represented a possible danger to national security.

The security service took a different view of the WhatsApp conversation and believed the messages showed more than someone simply making angry comments.

According to the information presented during the legal proceedings, MI5 believed J4 had shown an intention to carry out Islamist terrorist violence, either in Britain or abroad.

The situation became more serious after J4 travelled outside the United Kingdom using his British passport.

Following his departure, MI5 officials recommended that the government remove his British citizenship because of the security concerns surrounding him.

The government subsequently made the decision to deprive him of his citizenship.

J4 was informed that he had lost his British nationality and was instructed to return his British passport within 31 days.

However, the court heard that he did not surrender the document as instructed. Instead, he kept the passport and later used it to obtain residence permits in other countries.

His decision to continue using the passport became another issue considered during the proceedings.

J4 challenged the government’s decision, arguing that the authorities had misunderstood his comments and that he had never seriously intended to attack anyone.

His legal representatives told the commission that he was the type of person who sometimes made careless or exaggerated statements without thinking about the consequences.

They argued that his WhatsApp messages should not have been treated as proof that he genuinely intended to carry out violence.

In their view, the conversation showed someone speaking recklessly rather than preparing to commit a terrorist attack.

However, the judges were not persuaded by that explanation.

After examining the messages and the wider evidence, they concluded that it was reasonable to infer from his words that he intended to attack Paludan.

The commission therefore rejected his attempt to overturn the citizenship deprivation decision.

As a result, J4 will not regain his British citizenship through this appeal.

The decision was made despite the fact that members of his immediate family, including his mother and brothers, continue to live in the United Kingdom.

The court also decided that his real identity should remain hidden from the public.

Judges said the anonymity order was necessary to protect his personal safety, meaning his name cannot be published in connection with the case.

The man at the centre of the controversy, Rasmus Paludan, has been involved in several disputes across Europe because of his public demonstrations involving the Koran.

Paludan, 44, founded the Danish political party Stram Kurs, which means Hard Line, in 2017.

The party became known for its strongly anti-Islam position, while Paludan attracted international attention through demonstrations in which he publicly burned copies of the Muslim holy book.

His actions have repeatedly caused anger among Muslim communities and led to criticism from political leaders and members of the public.

In March 2023, Paludan posted a video announcing that he intended to travel to Wakefield and burn a copy of the Koran in a public square.

The announcement caused concern among local residents and officials, who feared that his visit could lead to serious tensions or disorder.

Local political figures, including Labour MP Simon Lightwood, opposed the proposed demonstration and supported efforts to prevent the visit.

The concerns were partly linked to what had happened during Paludan’s earlier demonstrations in other European countries.

In the spring of 2022, he travelled to several locations across Sweden, where he organised public demonstrations involving the burning of the Koran, including in areas with large immigrant populations.

His actions triggered widespread anger and were followed by violent counter-protests and riots in parts of the country.

Police officers were injured, vehicles were damaged, and authorities faced serious challenges trying to restore order.

Paludan has also faced legal problems over his conduct.

In November 2024, he was sentenced to four months in prison after being convicted of two counts of incitement against an ethnic group and one count of insult.

Earlier, in 2020, he received a one-month prison sentence, suspended for two months, after being found guilty of 14 offences, including racism, defamation and dangerous driving.

His activities also resulted in restrictions on his movements across Europe.

In 2020, French authorities expelled him after he indicated that he intended to burn a copy of the Koran in Paris.

He was also arrested and expelled from Belgium and received a two-year entry ban from Sweden.

Despite the controversy surrounding Paludan’s behaviour, British security officials treated the alleged threat against him as a separate and serious national security matter.

The case highlights the difference between a criminal prosecution and a government decision based on national security concerns.

Although the Crown Prosecution Service decided not to bring criminal charges against J4, MI5’s assessment played an important role in the government’s decision to remove his citizenship.

The outcome also shows that a person can face serious immigration and nationality consequences even when an investigation has not resulted in a criminal conviction.

However, removing British citizenship is a major legal step and must meet the requirements set out in UK nationality law, including restrictions designed to prevent unlawful deprivation of citizenship.

For J4, the latest ruling means that his attempt to regain British citizenship has failed, even though his close family members remain in the country.

His case has also drawn attention to how comments made in private online conversations can become important evidence in national security investigations.

What began as a WhatsApp discussion about a controversial political demonstration eventually developed into a major legal dispute involving MI5, the British government and the courts.

The commission’s decision leaves the government’s citizenship deprivation decision in place, marking a significant outcome in a case that began with a series of messages about a planned Koran-burning demonstration in West Yorkshire.
