An Irish businessman last night said he is "shocked and appalled" at the conditions found in UK-based care homes and hospitals owned by his investment firm.
The statement came as a probe into the Castlebeck group found that over 200 people with mental disabilities had been subject to inhumane and substandard care.
Castlebeck is 80pc owned by former Kerry Group chief executive Denis Brosnan's Swiss-based Lydian Capital Partnership -- whose shareholders include JP McManus and John Magnier.
In a statement to the Irish Independent, Mr Brosnan promised that auditors PWC would undertake a full review of the company's services.
Earlier this year, an investigation found evidence of widespread abuse of patients at the Castlebeck-owned Winterbourne View home in Bolton.
Twelve people who worked at the hospital were subsequently arrested.
A follow-up report found that more than half of the group's 23 facilities were failing to meet legally binding standards.
