Geoffrey Mosiria, the Nairobi City County Chief Officer for Citizen Engagement and Customer Service, has declared his intention to contest the Nairobi governor seat in the 2027 General Election. Mosiria made the declaration on Sunday, October 11, 2026. He is the latest entrant in a growing field that includes the incumbent, Johnson Sakaja. Mosiria's decision to run for governor was announced on the same day he met former Interior Cabinet Secretary Fred Matiang'i.
Mosiria proposed Margaret Wanjiru, a former Starehe MP and the leader of Jesus Is Alive Ministries church in Nairobi, as his running mate during a church service. He addressed congregants at the church, presenting his county service record as the basis of his candidacy. Mosiria claimed credit for establishing Nairobi's first intensive care unit and ensuring the availability of medicine in the county. However, these claims have not been independently verified.
Mosiria's entry into the governor race adds another contender to the growing list of aspirants. The incumbent, Johnson Sakaja, is seeking to retain his seat. Other listed contenders include Embakasi East MP Babu Owino, Kasarani MP Ronald Karauri, businesswoman Agnes Kagure, Embakasi North MP James Gakuya, Wanjiru, Makadara MP George Aladwa, and KANU spokesperson Tony Gachoka.
Mosiria urged aspirants to campaign on policies rather than violence or drugs, and to engage voters directly instead of deploying gangs. He also claimed to have helped many young people in Nairobi, which he believes has earned him support from women. Mosiria's later posting to customer care was a turning point, he said, as he found children and mothers in distress and began assisting them.
The exact purpose of Mosiria's meeting with Matiang'i beyond attending the church service was not established. Whether Wanjiru has accepted the running-mate proposal also remains unclear. Mosiria told the congregation that if elected governor, he would want Wanjiru as his deputy, arguing the combination would move the county forward.
Mosiria presented his experience working in different departments, including health and customer care, as a qualification for the governor seat. He said he encountered resistance as he rose through the ranks but continued working. Mosiria also said he would return to the church at the same time next year to thank congregants should he be elected.
With Mosiria's entry, the Nairobi governor race has become more crowded. The contestants will need to differentiate themselves based on their policies and leadership experience. Mosiria's proposal of Wanjiru as his running mate could potentially bring in more supporters, particularly from the church community.
