A third of care and nursing homes in England do not meet all the necessary standards, according to the Care Quality Commission.

The regulator said it was determined to identify poor care earlier.

As well as introducing specialist inspectors and gathering more information from families and staff, it has told Panorama it will look at death rates in homes.

Mandy Mugford was so worried, she chose to secretly film the care of her mother, Margaret.
