Summary
The UK government acknowledged it is investigating a cyber incident after media reports suggested that a hacking group linked to China may have accessed thousands of confidential documents held by the Foreign, Commonwealth and Development Office. Officials said the inquiry indicates a fairly low risk that personal information has been compromised, while noting that allegations of visa‑related data exposure remain unverified. The situation arises amid efforts to reset Britain’s relationship with China, which has been strained by concerns over espionage and human rights issues, and while decisions on a proposed Chinese embassy in London have been postponed.

Description
The UK government acknowledged on Friday, December 22, 2025, that it is investigating a cyber incident following media reports. Trade Minister Chris Bryant stated that the investigation had begun in October. He said the government believes there is a fairly low risk that anyone's personal information has been compromised. Bryant also characterised the allegations linking the incident to China as pure speculation and said he did not want to inflame further speculation. He noted that it remains speculative whether the incident relates directly to China.
Media reports, specifically from The Sun newspaper, alleged that a hacking group known as Storm 1849, which is linked to the Chinese government, may have gained access to information related to tens of thousands of visas. The reports also claimed that hackers linked to China had accessed thousands of confidential documents held by the Foreign, Commonwealth and Development Office. The allegations emerged at a sensitive time in Britain's relationship with China, as Prime Minister Keir Starmer's government seeks to rebuild trade and diplomatic links that have been strained by concerns about Chinese spying and human rights abuses. Starmer is reportedly planning to travel to China in late January 2026, which would be the first visit by a British prime minister since 2018.
In response to the situation, the government has delayed a decision on China's plans to build a massive new embassy in London amid criticism that the facility could be used as a base for espionage. Bryant said the government is taking a pragmatic approach to its relations with China, recognising areas where the two countries can cooperate and others where Britain must challenge Beijing. He emphasised that the relationship with China must be conducted with eyes wide open, a stance the government has maintained from the outset.
