Why did Raila Odinga challenge the 2022 presidential election results?

Raila Odinga challenged the results of the 2022 presidential election due to concerns regarding the integrity of the vote-tabulation process and allegations of electoral malfeasance.12

Specifically, Odinga’s challenge was prompted by the following factors:

• Lack of Transparency: Four of the seven commissioners of the Independent Electoral and Boundaries Commission (IEBC) refused to validate the results, characterizing the final stage of the tabulation process as "opaque".12
• Verification Issues: Odinga’s election agents reported that they were unable to verify certain results and cited concerns regarding the conduct of the process.1
• Alleged Discrepancies: In his petition to the Supreme Court, Odinga alleged that the results were fraudulent, citing discrepancies between voter turnout figures and the final election results, as well as claims that some votes were not properly tallied.1

While Odinga sought to have the results overturned, the Supreme Court of Kenya ultimately upheld the election of William Ruto on September 5, 2022, ruling that no credible evidence of fraud had been presented.12
