More than 158,000 people have signed up to help Britain's National Health Service tackle the coronavirus outbreak just hours after a request for a quarter of a million volunteers, ITV said.
The health ministry and NHS declined immediate comment.
The death toll from coronavirus in the United Kingdom jumped on Tuesday by 87 to a total of 422 - the biggest daily increase since the crisis began.
Britain had called for 250,000 volunteers to help the NHS and vulnerable people hit by the coronavirus crisis.
