Conservative Stephen Dorrell, chair of the Health Select Committee, said he did not believe that the CQC had succeeded in its objective to ensure public confidence in acceptable standards of care and patient safety.
He added: "Public confidence in the CQC was further undermined last year by its failure to address issues identified within its own management, organisation, functions and culture by its own board member Kay Sheldon."
"It is essential that the CQC reforms its culture and working practices to address these shortcomings.
"The new CQC Chair must, as a matter of urgency, overhaul its governance structures to ensure the board sets clear objectives for the organisation, holds the executive effectively to account against these objectives, and regularly assesses its own performance and effectiveness."
