Outgoing Auditor General Edward Ouko (pictured) has dismissed speculation that he's been offered a job as Treasury CS.

Ouko, whose eight-year non-renewable term ended on Monday, remained mum about his future but said he would continue fighting corruption and impunity.

"I have not been approached by anybody for anything," Ouko said on Tuesday.

He added: "There's still so much to do and I think it's our collective responsibility whether you're in government or not for the fight corruption and impunity to continue."

Mr Ukur Yatani is acting Treasury CS after Henry Rotich was charged in relation to the Sh63 billion dams scandal.

Ouko was speaking at the University of Nairobi and described the job of Auditor General, which he was at first reluctant to take, as "the most fulfilling in his life."

One of the challenges that confronted him when he took over the office, Ouko said, was unmotivated workforce due to poor salaries.

"Most of the staff were unreceptive to technology. However, I worked hard to change the situation. I had to do something about mind set change," said Ouko.

Ouko said he has left solid systems to prevent his staff being compromised.

He said no audit could be deleted or anyone try something fishy because notifications and time stamps would show when anyone logged in.

Ouko also proposed that in future the auditor general should be allowed to make statements during budget readings highlighting how the previous budget was spent.

"Otherwise we may end up with budgets continuously loaded with wastage," said Ouko.

He also proposed that serious lifestyle audits be taken to counties.
