Ferdinand Waititu was on officially sworn-in as Kiambu Governor in a colourful event at Ndumberi grounds.
National and county leaders led by outgoing governor William Kabogo attended the ceremony.
Waititu took the oath of office alongside his deputy governor James Nyoro.
The outgoing Kabete MP won the seat after beating Kabogo who vied as an independent candidate.
Kabogo went to the polls after losing in the Jubilee Party nominations held in April.
The two leaders showed political maturity and shared jokes about the task waiting the incoming governor.
Kabogo, in his congratulatory message, wished Waititu well and offered to support when called.
“Today, I handed over the instruments of power to the incoming governor of Kiambu, Ferdinand Waititu.”
“I ask everyone to support him and his new administration in moving Kiambu forward,” he said.
“#TujengeKiambu is for everyone of us. God bless Kiambu, God bless Kenya.” Kabogo added.
“We must work together or we will perish together as fools,” he told the gathering.
Some of the leaders who attended the ceremony include Kabogo’s deputy Gerald Githinji.
Cabinet Secretaries Joe Mucheru (ICT) and Sicily Kariuki (Gender and Youth Affairs) attended the ceremony.
Kiambu senator-elect Kimani Wamatangi and all MPs recently elected in the county were also present.
Others included Nakuru governor-elect Lee Kinyanjui and President Uhuru Kenyatta’s uncle George Muhoho.
