What we currently know of the electronic tagging scandal is based on a government-commissioned audit by PricewaterhouseCoopers. It concluded that:
- Ministry of Justice was billed for tagging of people who were in prison, had left the country and who had never been tagged in the first place. In a few cases, the subject had died.
- Charging continued for many months, and even years, after it should have
- Alleged overcharging dates back to at least 2005, and possible 1999
- Incorrect bills run into the low tens of millions
Justice Secretary Chris Grayling has said he has found "no information to confirm that dishonesty has taken place on the part of either supplier," but added that he wants an investigation to look into this.
