As a result, five Cabinet Secretaries stepped aside. They are Mr Kamau, Mrs Ngilu, Mr Kazungu Kambi (Labour), Mr Davis Chirchir (Energy) and Mr Felix Kosgey (Agriculture). None has been reinstated although formal cases are yet to be lodged.
From its own analysis, the anti-graft commission has completed 24 per cent of the high profile cases in the last financial year, while 45 per cent are still under investigation and 26 per cent are undergoing analysis before deciding whether or not they will be prosecuted.
Among cases handed over to the Director of Public Prosecution is that against former Judiciary Registrar, Mrs Gladys Boss Shollei, and three other officials, Mr Kakai Kissinger, Mr Martin Okwata and Mr Benedict Omolo.
Another involves former Investment Secretary Esther Koimet who is alleged to have used her office to deprive former employees of the Kenya Railways Corporation of houses set aside for them to buy under a tenant-purchase scheme.
And among the cases whose evidence is being analysed are scandals at the Ministry of Lands, Ministry of the Environment and the Mumias Sugar Company.
In the Mumias case, it is alleged that Dr Evans Kidero, now the Nairobi Governor, paid a law firm associated with Mr Tom Ojienda Sh280 million for services not rendered. The money was allegedly paid into Mr Ojienda’s private bank account. Mr Ojienda is seeking to stop the commission from investigating his bank account.
Others involve investigations into the alleged loss of Sh50 million in the office of Deputy President William Ruto, which was irregularly used to buy lifts, allegations that Sh100 million was used to hire a private jet that was used by Mr Ruto to visit five African countries and allegation of double payment for the renovation of his office and residence.
It is also alleged that the office misappropriated Sh200 million, half of which was used to mobilise MPs to impeach Devolution Cabinet Secretary Anne Waiguru. The impeachment Motion was later shelved.
Besides the investigations into corruption cases, the commission says it also received 9,294 requests to conduct background checks on individuals nominated for state and public offices.
March and April this year had the highest number of requests at 1,866 and 1,373.
The requests were made as part of the constitutional requirement for vetting before the appointment of chief executives of State corporations and heads of various government departments.
The report dated July 23 will now be analysed by the House committee chaired by Mr Samuel Chepkong’a.
