A police-led review into high death rates at the former Stafford Hospital has found there is not enough evidence to prosecute any individuals.
Staffordshire Police said material relating to the deaths of 214 patients between 2005 and 2009 was reviewed.
Deputy Constable Nicholas Baker said there were “no grounds” for a criminal investigation against any individual clinician or manager at the trust.
He said this did not detract from the “appalling care” many suffered.

The review was set up in 2013 and led by a panel which included the South Staffordshire Coroner and the Crown Prosecution Service.
