Former Judiciary Chief Registrar Gladys Shollei has denied any involvement in the "Chickengate" bribery scandal, saying she had no role in procurement.
She said she wrote to the UK’s Serious Fraud Office asking for investigations once the matter was reported by the media.
Ms Shollei served as a deputy chief electoral officer at the defunct Interim Independent Electoral Commission (IIEC).
She said the only documents she signed were "a few" local purchase orders.
"I signed that on behalf of the chief executive officer, who was in India at that time," she told journalists at the Ethics and Anti-Corruption Commission (EACC) headquarters, after emerging from a grilling session that began at around 8am and ended at 11am.
"My role was elections operations, voter registration and education. Procurement, finance and human resource fell under the CEO," said Ms Shollei.
She also accused the EACC of "playing to the public gallery" by parading "innocent people” to court while the guilty were walking scot-free.
"Chickengate" is the name Kenyan media have given to a multimillion-shilling corruption scam in which a British firm paid out bribes codenamed "chicken" to officials of the IIEC and the Kenya National Examinations Council to secure deals.
