The MP for Barrow and Furness said he was disappointed there would be no inquiry into the alleged Care Quality Commission cover-up.
The initial review highlighted the CQC's failure to investigate a spate of baby deaths at Furness General Hospital.
This is disappointing given the seriousness of the cover-up at the CQC and its impact on Barrow families but the police ultimately had to make an assessment of whether they thought prosecutions could be brought successfully.
However, the decision not to include the CQC in the police probe does leave the path clear for these shocking failings to be included in the independent inquiry that will shortly begin and I hope its chair will agree to my request to do that.
Senior managers accused of a cover-up at the Care Quality Commission will not face a police inquiry, Cumbria Police said.
Officers will not investigate the health regulator for failings identified in an independent report which said there was "persuasive evidence" that senior officials ordered a damning internal review to be deleted.
The review highlighted the CQC's failure to investigate a spate of baby deaths at Furness General Hospital.
And the latest independent review, conducted by management consultants Grant Thornton, implied that the former chief executive Cynthia Bower, her deputy Jill Finney and media manager Anna Jefferson backed the suppression of the internal review.
A Cumbria Constabulary spokeswoman said the failure to act on the internal review "had no consequences for the health care provision for the people of Cumbria".
Cumbria police won't investigate the CQC over its alleged failure to act on concerns about Morecambe Bay Trust, including Furness General Hospital, as highlighted in the Thornton Report. The force were already investigating a number of deaths at the hospital.
Two hospital trusts in the north west will be the first to be targeted by new inspection teams aimed at improving patient care across the country.
Like most hospitals, Salford Royal, placed in the low risk category, and the Royal Liverpool and Broadgreen, placed in the "Variety of risk points in between" category, will face visits from larger groups of medical experts than before and trained members of the public.
The improvements follow the national health review carried out by Bruce Keogh and the Care Quality Commission's appointment of a new inspector.
