ADVERT 
ADVERTNairobi County Chief Officer Geoffrey Mosiria has officially declared his intention to contest the Nairobi gubernatorial seat in 2027, positioning himself as a hands-on administrator who says his experience across key county departments has prepared him to tackle the capital’s persistent challenges.
Nairobi’s 2027 gubernatorial race is gathering momentum after County Chief Officer for Citizen Engagement and Customer Service Geoffrey Mosiria declared his interest in succeeding Governor Johnson Sakaja, promising to overhaul the capital if elected.
Mosiria announced his bid on Sunday, October 11, during a worship service at Jesus Is Alive Ministries Church, hosted by Bishop Margaret Wanjiru, where he presented his record in county administration as the foundation of his leadership ambitions.
Confident of his ability to deliver change, the outspoken county official cast himself as a problem-solver whose experience in healthcare, environmental management and customer service had given him a practical understanding of Nairobi’s needs.
“I have done a lot of work in Nairobi. I have worked in health, where I ensured that we have the first ICU and medication in Nairobi that is working until today,” Mosiria said.
ADVERTHe explained that his subsequent deployment to the environment docket exposed him to the challenges of maintaining cleanliness and enforcing county regulations in a city grappling with waste management, pollution and persistent public sanitation concerns.
His tenure in the environment department was marked by highly visible enforcement operations against individuals and businesses accused of violating county regulations. Mosiria frequently documented such interventions on social media, building a public profile that extended beyond the traditional boundaries of county administration.
In November 2025, Governor Sakaja reassigned him to head Citizen Engagement and Customer Service, a position that has brought him into closer contact with residents seeking assistance from the county government.
Mosiria said the role had enabled him to intervene in cases involving vulnerable women and children, arguing that his accessibility and willingness to respond to public complaints demonstrated his readiness for higher office.
He claimed that his work had earned him recognition among Nairobi women, whom he said viewed him as a leader because of his commitment to addressing their concerns.
“The women in Nairobi declared that I am their leader because I love and have rescued them. I work 24/7 to ensure that everything is in order,” he said.
Mosiria argued that the responsibilities he had shouldered as a chief officer were comparable to some of the demands placed on the governor, adding that occupying the county’s top office would give him greater authority to implement his vision.
“Nairobi residents have told me that I hold a small office but I am doing work that equates to that of the governor. When given the governor seat, I will transform the city,” he declared.
‘I WILL FIX THIS CITY’
With his campaign now taking shape, Mosiria is seeking to turn his reputation as an outspoken county official into a broader political movement centred on service delivery and visible action.
Declaring himself the candidate capable of delivering change, he adopted the slogan of a fixer determined to confront Nairobi’s longstanding problems.
“If you want change in Nairobi, Mosiria is the change, I will fix this city. In front of you is Mr Fix It,” he said.
His declaration places him in a political contest that is likely to revolve around Nairobi’s most pressing concerns, including garbage collection, drainage, traffic congestion, public health, insecurity, informal settlements and the quality of essential county services.
However, translating a record of departmental interventions into a successful gubernatorial campaign will require more than personal visibility. The race will test his ability to articulate a comprehensive development agenda, build a countywide political network and convince voters that his proposed solutions can deliver measurable improvements in their daily lives.
REJECTS POLITICAL VIOLENCE
Mosiria also used the church service to challenge politicians seeking elective positions to campaign on their ideas rather than resort to intimidation or violence.
He urged aspiring leaders to sell their policies to voters, warning against the use of goons to advance political ambitions.
“To everyone who wants leadership positions, go ahead and sell your agenda to Kenyans, don’t work with goons,” he said.
Expressing confidence in his electoral prospects, Mosiria promised to return to the church for a thanksgiving service if voters endorsed his bid in next year’s election.
“Next year, I will come back here a day like this for thanksgiving for electing me,” he added.
His remarks place peaceful campaigning and issue-based politics among the themes he wants associated with his political brand as the 2027 contest approaches.
BACKS MATIANG’I FOR NATIONAL LEADERSHIP
Beyond his Nairobi ambitions, Mosiria expressed support for former Interior Cabinet Secretary Fred Matiang’i, describing him as a leader chosen by God and citing his experience in the education and interior security dockets.
The endorsement signals Mosiria’s willingness to connect his county-level political ambitions with the wider national political realignments expected ahead of the 2027 General Election.
Whether that political association will translate into a tangible advantage in Nairobi remains to be seen as alliances, party tickets and campaign strategies take shape.
FROM ENFORCEMENT OFFICER TO GOVERNORIAL ASPIRANT
Mosiria’s political profile has grown through his work in the Nairobi County Government, particularly during his tenure in the environment department, where he became known for publicised enforcement operations.
His reassignment to Citizen Engagement and Customer Service in November 2025, under changes announced by Governor Sakaja, shifted his responsibilities towards handling public concerns and improving interactions between residents and the county administration.
The changes were communicated through a circular dated November 18, 2025, issued under Section 45(5) of the County Governments Act, 2012.
His gubernatorial declaration now marks a significant step from county administration into elective politics, setting the stage for a campaign in which he will have to demonstrate that his personal brand of direct intervention can be translated into an effective citywide government.
For Nairobi voters, the central question will be whether Mosiria can turn his promise to be the capital’s Mr Fix It into a credible programme for better services, accountable leadership and sustainable urban development.
With the 2027 General Election approaching, his entry adds another dimension to the contest for control of Kenya’s capital, where political ambition will ultimately meet the hard test of voter expectations and the city’s everyday challenges.
