Surrey County Council said an "urgent" investigation is already underway following the death of a pensioner after her nursing care was cut off.
Surrey County Council was responsible for replacing Gloria Foster's nursing care after a police raid closed down the Sutton-based company, Carefirst 24, which had looked after her.
A county council spokesperson said:
We're very sad to hear about Mrs Foster's death, and our thoughts are with her family and friends at this difficult time.
The safety of vulnerable adults is our top priority, which is why this tragic event is already being urgently looked at by the Surrey Safeguarding Adults Board.
