A significant scandal has emerged involving rogue scientists from three hospitals in China who attempted to sell the confidential medical data of half a million NHS patients. The sensitive details, originating from the UK Biobank – a research hub providing 'de-identified' data to universities, institutes, and private companies – were reportedly listed for sale on Alibaba, an e-commerce platform likened to China's Amazon. This incident has ignited widespread concerns regarding Britain's allegedly 'lax' security measures and insufficient regulations, which critics argue gave Chinese academics extensive access to the entire UK Biobank database.

The individuals from these three distinct Chinese research hospitals initially accessed the data legitimately. However, they subsequently proceeded to list it for sale. The UK Biobank, a registered charity, refrained from disclosing the names of the medical facilities involved but confirmed that their access to the data has since been revoked. The charity indicated that an anonymous whistleblower provided the tip-off about the listings. A Whitehall source sharply criticized the UK Biobank, stating it had been 'very, very lax' in managing data access and ensuring its security.

The stolen data did not encompass names, addresses, or direct contact information. However, it contained other highly personal details, including gender, age, month and year of birth, assessment centre data, attendance records, socioeconomic status, and lifestyle habits. Technology minister Ian Murray publicly announced the data leak and the attempted sale, condemning it as an 'unacceptable abuse' and triggering immediate calls for a public inquiry.

This current breach follows a previous outcry last year when plans to grant Chinese researchers access to the GP records of 503,000 UK Biobank volunteers became public. At that time, Members of Parliament, security experts, and former spy chiefs issued strong warnings against the decision. They voiced fears that such access could offer a 'window into strategic aspects of the nation's life' for a potentially hostile state, raising concerns that China might leverage this information for developing biological weapons and enhancing its status as a biotech superpower.

In light of the recent breach, the UK Biobank has temporarily suspended global access to its data to prevent any further unauthorized downloading and reselling of information. Although the listings on Alibaba were removed before any sales could be finalized, experts speculate that Beijing may have already exploited the information. Professor Luc Rocher from the Oxford Internet Institute underscored the gravity of the situation, revealing that this constitutes the '198th known exposure of UK Biobank data since last summer' and pointing out that stolen data often remains accessible online for download.

Shadow national security minister Alicia Kearns accused the government of handing a 'gift to China' that could jeopardize lives. She demanded answers regarding which institutions had their access revoked, which had ties to the Chinese state, and who authorized overriding MI5's warnings from the previous year. Last April, NHS England conducted an audit of UK Biobank's international data sharing processes, including those pertaining to Chinese applications, which the Biobank successfully passed. However, in February, Health Secretary Wes Streeting's decision to permit the sharing of coded GP data from all volunteers with UK Biobank shocked security experts. Former MI6 spy chief Sir Richard Dearlove drew parallels to the controversial decision surrounding Huawei's role in the UK's 5G network. Sir Ken McCallum, head of MI5, has consistently cautioned against Chinese interference in science and technology, urging vigilance in forming international partnerships. Former Tory leader Sir Iain Duncan Smith also called for an inquiry, questioning the rationale behind granting China access to sensitive medical data, especially amid concerns about bioweapons development. Professor Sir Rory Collins, UK Biobank chief executive, offered an apology to participants for the concern this incident would cause.
