David Cameron is preparing to announce a full public inquiry into the Mid-Staffordshire hospital scandal.
The move is a victory for campaigners and The Sunday Telegraph, which has called for relatives of patients who died to be consulted on what went wrong.
Previous inquiries into the scandal have been denounced as whitewashes because they were not held in public.
Hundreds of patients died needlessly of appalling standards of care, exposed in a report from the Healthcare Commission, a watchdog, last March.
Targets on waiting times were blamed, as well as managers trying to clear debts in order to gain Foundation Trust status.
Campaigners have long been calling for a full inquiry into the failings and will welcome the decision to allow public hearings. The Prime Minister is expected to announce the move in the coming days
