Shamed businesswoman Anne Ganley "abused her power" and "criminalised decent people" by getting staff to take her speeding points, a senior police officer has said.
Anne Ganley OBE, 59, of The Cedars, Sunderland pleaded guilty to conspiracy in connection with 14 offences. She has been jailed for 30 months.

Superintendent Nicola Musgrove of Northumbria Police said the case served as a warning to others.
She said: "I hope this shows that no one is above the law and for someone such as Anne Ganley who has been so well-respected in the community has shattered her reputation and completely abused her authority and I'm sure people of Sunderland and beyond with be outraged and hugely disappointed in her.
"She has criminalised decent people."
All those convicted were arrested as part of Operation Jersey which began in March 2013 after intelligence led police to investigate Ganley in relation to speeding offences.
It was suspected at the time that Anne Ganley was paying employees to accept responsibility for speeding offences on her behalf.
It was also believed Ganley's son, Brent Ganley, was carrying out similar offences.
After a day of action, in December 2013 eight people were arrested, including Anne Ganley and Brent Ganley and a number of warrants were carried out at commercial and residential properties. This led to further information being gathered and as a result a further 13 people arrested.
Supt Musgrove has praised her team for the excellent detailed investigation carried out and says people in the community will be outraged by Ganley's actions.
She said: "This has been an intricate and sensitive case that has hugely impacted on the lives of those who have sadly been dragged into this ordeal.
"The team has done a fantastic job in getting to the bottom of this investigation and now, Anne and Brent Ganley are now serving a prison sentence for their selfish actions.
