Mark Samuel Muriithi Mwenje (born 1985) is a Kenyan lawyer and politician serving as the Member of Parliament for Embakasi West Constituency in Nairobi County. He was elected in the August 2022 general election on a Jubilee Party ticket, unseating incumbent George Theuri of UDA, and is listed in the 13th Parliament as the constituency’s MP. In May 2023, the Azimio coalition and Speaker Moses Wetang’ula confirmed him as Deputy Minority Whip in the National Assembly, replacing Sabina Chege and making him one of the key opposition whips in the House. Professionally, Mwenje is an Advocate of the High Court of Kenya, Commissioner for Oaths and Certified Public Secretary, with a practice focused on corporate, commercial and conveyancing law. Before his election he was a partner and later Managing Partner at Mwenje & Karanja Advocates, following an earlier stint at Sichangi Partners Advocates. In Parliament, his interventions often centre on land justice, regularisation of long-term squatters, urban planning and service delivery in Nairobi’s dense estates, as seen in his Motion on voluntary regularisation of land occupied by squatters and petitions on land disputes in Dandora/Mowlem.
MP for Embakasi West (2022–present): Elected in 2022, defeating two-term MP George Theuri and bringing the seat under Jubilee within the Azimio coalition.
Deputy Minority Whip, National Assembly (2023–present): Confirmed by Speaker Wetang’ula in October 2023 as Deputy Minority Whip, positioning him at the centre of opposition strategy and House business management.
Leadership tussle over the Deputy Minority Whip seat (2023): His elevation to Deputy Minority Whip followed a protracted tussle over Sabina Chege’s position, with legal and procedural challenges that placed him at the centre of intra-Azimio and Jubilee disputes before Speaker Wetang’ula finally confirmed his appointment.
Factional Jubilee politics: As one of the most visible Jubilee MPs in Nairobi, he has been involved in rival alignments over the party’s direction, with some factions accusing colleagues of leaning toward the ruling coalition—tensions that periodically spill into media coverage and social media commentary.
News articles featuring Mark Mwenje
Managing Partner, Mwenje & Karanja Advocates: Co-founded and led a Nairobi-based law firm specialising in corporate, commercial, banking securities and real-estate transactions—experience he leverages in legislative debates on land, housing and investment.
Recognised high-performing first-term MP: Independent scorecards and commentary (e.g. Newsline/Mutembei-type rankings) have highlighted him among the better-performing Nairobi MPs within his first year, particularly on constituency visibility and land-justice advocacy.
High expectations on land and service delivery: Having anchored his politics on regularising land for squatters and addressing historical injustices in estates like Umoja, Kariobangi South and Mowlem, he faces strong scrutiny from residents and civil-society voices on whether motions and petitions translate into concrete titles, infrastructure and services.
No major corruption or criminal cases publicly reported: As of late 2025, there are no credible records of court convictions or formal integrity sanctions against him; public debate focuses more on coalition dynamics, performance and his role in contentious House leadership changes.
