Exclusive: Police seek more resources as number of allegedly suspicious deaths at Royal Sussex County hospital more than doubles

The number of patient deaths being investigated as possible manslaughter at a troubled NHS hospital has more than doubled to 90, the Guardian can reveal.

The growing number of allegedly suspicious deaths, up from an initial total of 40, has forced Sussex police to ask the Home Office for extra resources in dealing with its expanding inquiry into University Hospitals Sussex (UHS), known as Operation Bramber.
