Prime Cabinet Secretary Musalia Mudavadi's office has been allocated Sh300 million more than Deputy President Rigathi Gachagua's.
Treasury has allocated Mr Mudavadi's office Sh751.9 million for its recurrent budget in the revised 2022/2023 public expenditure plans compared to Mr Gachagua's office allocation of Sh450.85 million.
Meanwhile, the allocation to the Office of the President has been increased by Sh8.35 billion in the mini-budget.
The Office of the President had been allocated Sh23.1 billion in the budget whose preparation was overseen by former Treasury Cabinet Secretary Ukur Yatani, split into Sh17.08 billion for recurrent expenditure and Sh5.98 billion for development spending.
This has, however, been pushed up to Sh31.42 billion, of which Sh24.07 billion will be for recurrent expenditure while Sh7.35 billion will be for development expenditure.
Other than deputising President William Ruto, Gachagua's roles include chairing Cabinet committees and overseeing the implementation of decisions passed by the Cabinet.
His other roles are managing relations between the two levels of government and chairing the Intergovernmental Budget and Economic Council while also coordinating various committees.
The Prime Cabinet Secretary's roles include overseeing the Public Service Performance Management Unit and the government delivery services.
Besides assisting the president and his deputy, Mudavadi's roles include supervising ministries and state departments and coordinating the government legislative agenda with Parliament.
There have been claims that Mudavadi and Gachagua are embroiled in supremacy battles.
The reports gained traction, thanks to a war of words between Mt Kenya and Western leaders after Gachagua read the riot act to Nairobi Governor Johnson Sakaja over plans to kick out matatus from town and crack down on nightclubs.
But in an interview, two weeks ago, with The Standard, Mudavadi clarified that there was no bad blood between him and the deputy president.
"I don't know where the narrative that I am in a tiff with the deputy president is coming from. I see my role as complementary. When you are in government, you work as a team and the DP and I are working as a team.
"If there are any cross-cutting issues, there are mechanisms of dialogue that we can use to resolve those issues. I know very well that I am assisting the president and the deputy president," he said.
"Our roles are clearly defined."
Mudavadi, in the interview, dismissed reports of bad blood between him and Gachagua.
He also denied allegations of waging a silent war against the DP to elbow him out in President Ruto succession matrix.
