Police are being granted access to the details of people told to self-isolate by the government's Test and Trace scheme, Sky News has learnt.
The Department of Health and Social Care (DHSC) confirmed it had "agreed a memorandum of understanding with the National Police Chiefs Council (NPCC)" to provide forces with the information on a "case-by-case basis".
In a statement, a spokesman told Sky News: "It is a legal requirement for people who have tested positive for COVID-19 and their close contacts to self-isolate when formally notified to do so.
"The DHSC has agreed a memorandum of understanding with the NPCC to enable police forces to have access on a case-by-case basis to information that enables them to know if a specific individual has been notified to self-isolate.
"The memorandum of understanding ensures that information is shared with appropriate safeguards and in accordance with the law. No testing or health data is shared in this process."
