Starehe MP Maina Kamanda says that Water and irragation Cabinet Secretary is a statehouse project.
Kamanda sensationally claimed that seniour Jubilee officials within the statehouse have been forcing Wamalwa to the electorate.
Kamanda went ahead to warn that such moves may end up costing the coalition the Nairobi gubernatorial seat come election time.
"It is vital that we do not repeat the mistakes we did in the last elections.I know Wamalwa is a project from within the statehouse. These mistakes will cost Jubilee ," he told journalists on Thursday in Nairobi.
He called on Jubilee leadership to respect voters.
"If Jubilee will decide on it's candidates at the boardroom, there will be serious problems in future," he added in reference to Wamalwa's endorsement by some Jubilee members.
There has been speculations that Wamalwa has been fronted by Deputy President William Ruto to test the waters of Mt Kenya voting block as he eyes the presidency in 2022.
