The United Opposition Alliance, led by Wiper Party Leader Kalonzo Musyoka and DCP Party Leader Rigathi Gachagua, has alleged a government plot to rig Thursday’s by-elections through ballot stuffing and pre-marked ballots. IEBC Chair Erastus Ethekon dismissed these claims, insisting on the commission's impartiality.

• Kalonzo Musyoka claimed that 820,000 printed ballots for the by-elections were not properly serialized, and 30,000 pre-marked ballots were sent to Magarini, Malava, and Mbeere North.
• Rigathi Gachagua alleged that 1,500 gangsters would create chaos in Mbeere North to facilitate the insertion of 15,000 pre-marked ballots there, and an additional 10,000 to Malava.
• IEBC Chair Erastus Ethekon stated, "There are so many wild allegations which are not true, and we need to set the record straight," affirming the commission's commitment to a credible electoral process.

Former Cabinet Secretary and Democratic Party-Kenya (DP-K) Party Leader Justin Muturi has criticized the IEBC's decision to deploy plain-clothed police officers during the November 27, 2025, by-elections, calling them "state-sponsored goons." The IEBC announced it would deploy both uniformed and un-uniformed officers to ensure security amid violence allegations.

• Justin Muturi claimed plain-clothed officers would be "goons" hired by the government, operating under police protection.
• The IEBC, through Commissioner Alutalala Mukhwana, confirmed the deployment of both uniformed and un-uniformed police officers for the by-elections.
• Muturi urged IEBC boss Ethokon Edong to instruct the Inspector General of Police that all deployed officers must be identifiable and in uniform to prevent unregistered individuals from posing as law enforcement.
• The decision to deploy un-uniformed officers follows allegations of planned violence by political camps and incidents of violence, including gunshots and deaths, during the by-election campaigns.

IEBC Chairperson Ethokon Edong has issued stern warnings to candidates ahead of Thursday's by-elections, prohibiting them from bringing supporters or "goons" to tallying centers to ensure peace and integrity.

• Chairperson Ethokon Edong emphasized that only candidates, media, observers, party representatives, and senior party leaders will be allowed at tallying stations.
• Security measures, including deployments by the National Police Service, are in place to safeguard voters, officials, and election materials.

Kakamega Senator Boni Khalwale claims his security detail has been withdrawn and alleges a plot to arrest him ahead of tomorrow's by-elections. He links this action to his strong stance against certain senior government officials.

• Khalwale stated his security was "pulled without any warning or explanation" on Wednesday, November 26.
• He challenged police to come to his home, stating, "I have been arrested, teargassed and shot at for so many years."
• Trans Nzoia Governor George Natembeya raised similar concerns earlier on Wednesday, alleging his security was withdrawn around 12 am amid his criticism of President William Ruto's administration.
