John Njuguna Wanjiku, popularly known as “Ka-Wanjiku”, is the Member of Parliament for Kiambaa Constituency in Kiambu County. He first captured national attention in July 2021, when he won the Kiambaa parliamentary by-election on a United Democratic Alliance (UDA) ticket, defeating Jubilee’s Kariri Njama by a razor-thin margin of about 500 votes (21,773 vs 21,263). The win made him the first UDA MP in the Mt Kenya region, widely read as a symbolic breach of President Uhuru Kenyatta’s Kiambu stronghold by then–Deputy President William Ruto. He was comfortably re-elected in the 2022 general election, consolidating his status as a key Kenya Kwanza ally from Kiambu. Born in 1986 and raised by a single mother in Gatono village in Kiambaa, Njuguna often frames his story through the “hustler” narrative. Before politics, he worked in informal and business ventures and served as a lay preacher/evangelist, experiences he says shaped his grassroots connection. During the 2021 campaigns he reported being abducted and dumped in Burnt Forest, Uasin Gishu, allegedly for organising a Ruto event in Banana, Kiambu—an ordeal that further amplified his “persecuted hustler” image. In Parliament, he is an outspoken backbencher associated with the pro-Ruto wing, active on contentious legislation such as the Political Parties (Amendment) Bill and Finance Bills.
