Renson Mulele Ingonga has been appointed by President William Ruto to serve as the DPP.
Ruto highlighted that Ingonga will hold the job for eight years in a gazette notice on Wednesday.
A week after receiving approval by lawmakers following a thorough screening process, Ingonga was appointed.
Based on his overall familiarity with public litigations and his background working at the Office of the Director of Public Prosecutions for a number of years, the committee recommended his appointment in the vetting report.
Noordin Haji, who is now the Director-General of the National Intelligence Service (NIS), will be replaced by Mulele.
He held the position of Assistant DPP before being nominated.
