The undertaking was tendered by deputy public prosecutor Kamal Baharin Omar at the former prime minister’s 1MDB trial in the High Court here today.

“We need a specific date from the lawyers on when he (Ng) needs to attend court (if he has to testify),” said Kamal.

Lawyer Shafee Abdullah, representing Najib, said the defence would have to meet Ng first. “We will call him as a witness if deemed fit,” he added.

Last year, Najib’s lawyers informed the court that the defence intended to file an application to interview Ng.

Ng was sentenced by a New York court to 10 years in prison after a jury found him guilty of corruption in March 2023.

He was repatriated to Malaysia in October that year to assist local authorities in their bid to recover 1MDB assets.

According to Bukit Aman, Ng is still in police custody as more information is needed from him in the ongoing investigation into the recovery of 1MDB assets.
