Prime Minister Tun Dr Mahathir Mohamad made the announcement at a press conference today after a meeting of the Pakatan Harapan Presidential Council here.
Shukri went on mandatory retirement in 2016 when he was investigating several high-profile cases, including those related to 1Malaysia Development Berhad (1MDB).
Dzulkifli returned to serve at the Attorney-General's Chambers last Tuesday.
Dr Mahathir said the appointment of Shukri, who will assume duties after receiving the consent of the Yang di-Pertuan Agong, was based on the experience and information he had acquired during his service with the commission.
He has much information and he objected to the wrong actions of the MACC as well as the role of (former prime minister) Datuk Seri Najib (Tun Razak) in preventing investigations. We want to know exactly what happened, he said.
Dr Mahathir responded to a question seeking his comment on the meeting he had today with former MACC chief commissioner Tan Sri Abu Kassim Mohamed at the Perdana Leadership Foundation in Putrajaya.
Dzulkifli, who was appointed as MACC chief on secondment from Aug 1, 2016, to July 31, 2021, has returned to serve at the Attorney-General's Chambers.
