Campaigners for health reform are expecting the Government to announce a public inquiry into "disastrous" standards of care provided at an NHS hospital in Stafford.
Cure the NHS said it was anticipating that the inquiry into events at Stafford Hospital would be announced by Health Secretary Andrew Lansley in the House of Commons on Wednesday.
A spokesman for Cure the NHS, which has led a lengthy campaign for a full public inquiry, said members expected that the inquiry would be held under the Inquiries Act 2005.
The previous Labour government rejected calls for a full public inquiry into events at Stafford Hospital, instead ordering an independent inquiry.
That inquiry, which published its findings in February, found that the hospital "routinely neglected" patients and displayed "systemic failings" in its approach to care.
The independent report, chaired by Robert Francis QC, also found the Mid Staffordshire NHS Foundation Trust lost sight of its responsibility to provide safe care after managers became preoccupied with cost-cutting and Government targets.
The previous inquiry was launched after a Healthcare Commission report published last year revealed a catalogue of failings at the trust, which also runs Cannock Chase Hospital.
Appalling standards put patients at risk and between 400 and 1,200 more people died than would have been expected in a three-year period from 2005 to 2008.
A spokeswoman for the Department of Health confirmed that a statement was expected to be made in Parliament on Wednesday but declined to comment on its content.
