Because Karren Brady is the first person to ever lie on their CV.........
The wording is interesting however, it does't say she lied on her CV but her job application and there is a significant difference.
If you lie on a CV its not illegal just unethical (although if you get the job there are some jobs where certain lies would make it illegal, for example claiming you had a medical degree when you don't when applying for a job as a doctor).
If you lie on an Application form however its a different matter and it is illegal as you are being asked specifically certain questions so answering incorrectly is fraud.
So if Karen Brady lied on a Application form then she should be sent to prison for this
