John Koyi Waluke (born 1963) is a Kenyan politician and former Kenya Defence Forces officer who has served as Member of Parliament for Sirisia Constituency in Bungoma County since 2013. He first won the seat on an ODM ticket, later defected to the Jubilee Party, and in the 2022 general election he retained the seat for a third consecutive term on a Jubilee ticket, making him one of the party’s few surviving MPs in a region swept by the UDA wave. Before entering Parliament he served in the military from the early 1980s and later worked in business and public service, including a stint as director at the Coffee Board of Kenya and managing director of a private firm, while steadily building his profile in Bungoma politics. Over the years he has sat on key House committees such as the Public Investments Committee and the Departmental Committee on Administration and National Security, and has been a visible ally of figures such as Moses Wetang’ula and William Ruto in Western Kenya politics. Waluke’s political career has been dominated by a protracted legal battle over a controversial maize supply contract with the National Cereals and Produce Board (NCPB) through the firm Erad Supplies & General Contractors. In June 2020, the Anti-Corruption Court convicted him of fraud-related offences linked to a KSh 313–314 million payment and sentenced him to 67 years in prison or an alternative fine of about KSh 1 billion, a landmark judgment that briefly made him one of the most heavily sentenced sitting MPs in Kenya’s history. He secured bail and pursued a series of appeals: in October 2022 the High Court upheld the conviction and sentence, but in October 2024 the Court of Appeal set aside the 67-year jail term and multibillion shilling fine, ruling that payments made pursuant to a valid court order could not, on that basis alone, constitute fraudulent acquisition of public property. As of November 2025, however, the saga remains unresolved, with the Court of Appeal having recently directed that aspects of the over KSh 1 billion arbitral award and compensation dispute be re-examined by the High Court, ensuring that the maize case continues to shadow his legacy even as he serves his third term in Parliament.
