What happened

There have been further listings of confidential health records of UK volunteers on the Chinese website Alibaba since the breach reported last week, and the government is braced for further leaks, the science minister has said.

Why it matters

Addressing a House of Lords debate on the attempted sale of data belonging to 500,000 UK Biobank volunteers, Patrick Vallance said the government had worked with Chinese officials to remove additional postings on the online marketplace.

Common ground

“New listings will emerge – there have been additional listings posted since the government were made aware of the issue last week – and we continue to work with the Chinese government to remove them quickly,” Lord Vallance said.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
