However, the move was criticised by local councillors at the Cheshire East Council meeting on May 14 after they learned that the Council’s Health and Wellbeing Scrutiny Committee had not even been notified of the appointment. On May 15, Caring Together announced that Dame Williams and the Caring Together Executive Board had jointly decided that she would not be taking up the role.
