The National Super Alliance Coalition wants the investigators unravelling the dam scandal to name the perpetrators who have siphoned Sh21 billion from taxpayers.
In a statement seen by Standard Digital on Wednesday evening, Nasa questions the manner in which billions of shillings were paid without due diligence before earth movers were moved to construction sites.
A statement signed by Nasa CEO Norman Magaya also questions how TheTreasury cleared a Sh21 billion to the Italian firm CMC di Ravenna before ensuring that there was available land for the construction. It wonders how The Treasury bypassed crucial processes and on whose benefit was it acting.
"The only motivation for such irrational adventure was to facilitate quick payments of kickbacks to the perpetrators of monumental fraud," reads part of the statement.
The Kerio Valley Development Authority has also been accused of failing to conduct due diligence to ascertain the suitability of Italian firm CMC di Ravenna to do the job.
Nasa has accused KVDA of being influenced by powerful government officials to sanction payments of huge sums in a dubious deal.
"There is no way KVDA would have had the audacity to initiate payments for such projects without political support at the highest level of government," the statement adds.
The statement falls short of naming senior Rift Valley politicians as the masterminds of the deal.
Nasa states Arror and Kimwarer dam sites being in Elgeyo Marakwet, Rift Valley, there is a possibility that a powerful figure may have manipulated the KVDA to make controversial payments.
The statement reads: "It is improbable that all these transgressions could be executed without the knowledge and tacit facilitation of the senior politicians from the Rift Valley. The perpetrators of this scandal must have been working under a single powerful command in the execution of this fraud and plunder of public resources."
While urging Kenyans to support the Director of the Criminal Investigations George Kinoti in investigating and prosecuting perpetrators, the Coalition has however asked the DCI to make the following disclosures:
It wants the DCI to reveal identities of facilities that received material from suppliers in Eldoret and names of owners of the constructions sites. It also wants the name of the hotel that received towels bought at a cost of millions of shillings and proprietors disclosed. Also, the names of account holders who received kickbacks be revealed as well as the bank involved.
Further, it wants the DCI to reveal the name of the politician alleged to have bought land at Sh1 billion and later sold it to Government for Sh6 billion through proxies. Lastly, the National Land Commission and KVDA be compelled to disclose more details to the deal.
On Tuesday, The DCI gave a jaw-dropping account on how cartels transferred over Sh4 billion kickbacks to offshore accounts in Britain, Italy and then back to Nairobi.
Italian firm CMC di Ravenna is at the centre of Sh21 billion scandal which is the latest scandal to rock Jubilee Government after the 2017 General Election.
