AG claims ignorance on Auditor General's contract

This came to light when specially elected Member of Parliament (MP), Mephato Reatile raised a concern that the current Auditor General was hired on contract instead of on permanent basis, as the law states.

“I have observed that the Auditor General was hired on contract. Is this through your advice or what? The constitution is preaching the independence of that office. Why is it that the current Auditor General is working on contract?” Reatile enquired.
