LONDON — Police are conducting a criminal investigation into a dispute connected to the founding of Your Party, a left-wing political party that was established last year.

A spokesperson for London’s Metropolitan Police said it had launched an investigation after it received a report in September 2025 “relating to the alleged unauthorised access of a political party’s database.”

Officers recently arrested a man in his 20s on suspicion of an offence under the 1990 Computer Misuse Act, the spokesperson said. He was released pending further enquiries and has not been charged.

Officers also previously interviewed a woman in her 30s under caution in connection with the same investigation. The spokesperson added: “The investigation continues.”

Scotland Yard did not name any political party in its statement, and the spokesperson did not confirm which political party its investigation related to.

However, three other people with knowledge of the circumstances, all of whom were granted anonymity to discuss an ongoing case, said the investigation relates to a long-running dispute connected to the establishment of Your Party.

The left-wing party was co-founded in summer 2025 by the former Labour Leader Jeremy Corbyn and the former Labour MP Zarah Sultana, both of whom now sit as Your Party MPs in the House of Commons.

The two MPs clashed publicly over a September 2025 email that was sent to around 800,000 people on the new party’s mailing list, encouraging them to sign up as paying members. Sultana had promoted the membership portal while Corbyn described its launch as “unauthorised.” Sultana later said her sole aim had been to “safeguard the grassroots involvement that is essential to building this party.”

Neither the man arrested, nor the woman interviewed by police, are MPs and neither have been charged with an offence. Neither Corbyn nor Sultana are accused of wrongdoing.

A Your Party spokesperson said: “It would not be appropriate to comment any further about ongoing police investigations.”

They also said: “We can reassure our members and supporters that our systems are secure and that this was an isolated incident.”

The Trump administration has given its newly created “Super Intelligence Force” broad authority to determine how the tech industry and the federal government should address threats to national security and civil liberties posed by fast-evolving artificial intelligence technology, according to a charter obtained by POLITICO.

Three people familiar with discussions about the task force confirmed the document’s authenticity. The people were granted anonymity to share details that are not yet public.

The task force will identify “measures to improve the preparedness and response capability of both the government and the private sector to threats to the homeland and the American people,” the charter states. It will also produce a report on the risks of AI, focusing on “potential threats to civil liberties,” cybersecurity, standards for advanced models, and the impacts of possible overregulation.

The Wall Street Journal first reported on the details of the charter.

Both Silicon Valley and Capitol Hill were caught off guard by President Donald Trump’s announcement of the task force’s creation, with four tech-sector representatives telling POLITICO the industry was not widely informed beforeTrump’s social media post. Super intelligence is Trump’s preferred term for artificial intelligence.

The task force’s creation comes as major AI labs such as Anthropic and OpenAI have disclosed a spate of cybersecurity incidents related to new models with advanced hacking capabilities, sparking both industry leaders and lawmakers to call for a potential slowdown in AI development.

Director of National Intelligence Jay Clayton will lead the task force in his newly minted role as the administration’s AI czar, with Under Secretary of Defense Emil Michael, Office of Personnel Management Director Scott Kupor, and Federal Trade Commission Chairman Andrew Ferguson serving as vice chairs.

Its members include administration officials across the federal government, including at the National Security Agency and the Health and Human Services Department. Senior White House officials, including Vice President JD Vance and chief of staff Susie Wiles, will also be closely involved. Former Secretary of State Condoleezza Rice and venture capitalist David Sacks, who served as the administration’s AI czar until March, will also provide “advice” to the group on national security and technology, respectively.

The task force will stand for 120 days, but its work can be extended – or functions transferred to another government agency – at Wiles’ direction, per the charter.

The task force will undertake work spanning financial services, energy infrastructure, transportation, agriculture and emergency services, per the charter, and will work with the Pentagon, the Justice Department, the Homeland Security Department and the Federal Trade Commission to outline its recommendations.

The document also calls out two risk areas that have come under increased scrutiny in recent months: biosecurity and threats to the water supply. OpenAI recently threw its weight behind a slate of bills aimed at preventing AI models from exacerbating the threat of biological weapons, and rival lab Anthropic disclosed several incidents in which scientists in foreign countries used their models to research dangerous pathogens.

The Trump administration also rolled out a program in August to protect vulnerable U.S. water facilities from cybersecurity threats, following a series of cyberattacks on local water systems across the country.

The task force will also be responsible for reviewing “the current protocols and mechanisms in place” for AI labs to notify the government of breaches, hacks and jailbreaks, in addition to developing recommendations for improvements to the government’s response to such incidents.

The document refers to the technology “as both an amplifier and accelerant of both risks and opportunities” but ultimately places responsibility for any risks associated with AI on the labs developing advanced models.

“Though the labs are ultimately responsible for the risks and opportunities that their models amplify and accelerate, it is the role of the federal government to recognize and understand this era of change and to enforce our nation’s laws so that the fundamental principles of our Republic are safeguarded and advanced,” the document reads.
