It will be at the discretion of the Pardons Board to announce its decision, Saifuddin Nasution Ismail said at a press conference on immigration and labour issues, which was packed with media seeking news on Najib's clemency bid.
The disgraced former leader Najib is serving a 12-year jail term for graft linked to state fund 1Malaysia Development Berhad (1MDB), from which U.S. and Malaysian investigators estimate $4.5 billion was stolen and more than $1 billion channeled to accounts linked to the former premier.
Najib requested a royal pardon shortly after beginning his sentence in 2022 and after exhausting all other appeals. He consistently denied wrongdoing.
Malaysia's Minister in the Prime Minister's Department Zaliha Mustafa on Tuesday said the Pardons Board had met this week and an official statement would be issued, though she did not say if Najib's request was discussed.
The remarks prompted a blitz of media speculation, with one prominent Malay-language newspaper forced to withdraw a report citing sources saying that Najib had been granted a full pardon.
Najib's lawyer and representatives, as well as Malaysia's attorney-general, a member of the pardons board, did not respond to Reuters' requests for comment.
Officials on Wednesday declined to comment on further reports.
"Let us not jump the gun, let us wait for an official statement to be made," Communications Minister Fahmi Fadzil said at a separate press briefing.
"We must show professionalism in reporting."
U.S. and Malaysian investigators estimate around $4.5 billion was stolen from 1MDB, with more than $1 billion channeled to accounts linked to Najib.
Najib says he was misled by fugitive financier Jho Low and other 1MDB officials over the source of the funds and that he believed they were donations from the Saudi royal family. He remains on trial in several other cases linked to corruption at 1MDB.
Najib's daughter, Nooryana Najwa Najib, on Wednesday posted on Instagram a picture of the former leader sitting pensively, accompanied by the message "Always waiting for your return, however long it takes."
