Doctors at Imperial College hospitals will soon be monitoring the health of patients with an app developed by Google-backed AI firm DeepMind.

Streams came from a deal with London’s Royal Free hospital that gave Google access to 1.6 million patient records.

Medical data campaigners said patients deserved to know more about how their data was being used.
