The health and social care watchdog, the Care Quality Commission (CQC) has denied that it failed to take sufficient action after undercover filming showed an 80-year-old woman being assaulted by a care worker, which will be broadcast for the first time on BBC Panorama tonight.
These tiny and relatively cheap devices have revolutionised the filming of action sequences - you just clamp them to a bike, a car, or even a surfboard, press the button and hope you capture something exciting.
