President Uhuru Kenyatta on Wednesday vowed not to sign Parliamentary Service Bill, 2018 for higher salaries and allowances for legislators.
The perks that members of parliament intent to enhance are house allowances, car loans and insurance covers.
President Kenyatta, who spoke at Ndumberi Stadium in Kiambu County, said Kenyans are tired and annoyed by the behaviour by parliamentarians of increasing their earnings at their expense.
He said he does not care if his decision costs him the goodwill of the MPs.
"I have to say this ... and I know many people will get angry with me ... some things people are trying to pass in the assembly ... what I have heard wananchi saying is that they are tired of this behaviour," he said.
"I am in support [of wananchi] and even if you (MPs) hate me, I will not retreat. If you bring it (the bill), I will shoot it down."
The president went to Kiambu to launch Raisi Mashinani, a mobile service delivery unity.
On November 21, Mr Kenyatta rebuked leaders who always push for salary increases without considering the public.
He said Kenyans appreciate their leaders but that this should not be used to make them poor and cause them to suffer.
"With all due respect, everyone wants to live a good life, but before we as leaders live a good life, we should make sure our people get the best," he said.
He added, "Kenyans have no problem with you leaders increasing your salaries, but only if you would work on their situations first. Sadly, here you have a scenario of suffering Kenyans who, upon going through the local dailies, find that MPs, MCAs and all other leaders have increased their salaries."
On that day, the president said he did not want a war with anybody.
