Samuel Onunga Atandi is a Kenyan politician and economist from the Orange Democratic Movement (ODM) who has served as the Member of the National Assembly for Alego Usonga Constituency in Siaya County since 2017, winning re-election in 2022. Public profiles list his birthday as 13 March (year not publicly disclosed in official records). A former banker with deep experience in institutional and transactional finance, he has become one of Parliament’s louder voices on public finance, debt, taxation and regional development, often using the floor of the House and media interviews to push for more equitable resource allocation to counties and greater accountability in public spending. In March 2025, Atandi was elected unopposed as Chairperson of the National Assembly’s powerful Budget and Appropriations Committee, taking over from Kiharu MP Ndindi Nyoro and placing him at the centre of Kenya’s budget-making and fiscal-oversight process. Before entering politics, he spent about a decade in banking, rising from sales roles at Standard Chartered Bank to senior relationship-management positions at Bank of Africa and NIC Bank, and finally Director of Institutional and Transactional Banking at National Bank of Kenya. His supporters present him as a technocratic legislator leveraging private-sector experience to influence fiscal policy; critics, however, often focus on his combative political style and a series of high-profile clashes and allegations at the constituency and national level.
