Najib Abdul Razak lost his composure several times during an interview with Al Jazeera for its 101 East programme today, according to the media organisation.

In a press release, Al Jazeera said the former premier was quizzed on a slew of issues ranging from the “pink diamond” to the “RM2.6 billion donation” during the hour-long “grilling”.

Al Jazeera said Najib “lost his cool a couple of times” and the question regarding the pink diamond left him “visibly irritated”.

The interview was conducted by Mary Ann Jolley, whom the Najib-administration deported in 2015 while she was pursuing a story on the Altantuya Shariibuu murder.

When Jolley raised her deportation, Najib expressed no regret for doing so.

“Good thing we deported you. You are a nuisance. Because as far as I am concerned, making lies.

“Fabricating lies is not something we want to tolerate in this country,” said the former premier.

Jolley produced a 30-minute documentary titled "Murder in Malaysia", which attempted to shed light on the many unanswered questions surrounding Altantuya's murder.

Among others, the documentary claimed Sirul Azhar Umar - one of two former police commandos found guilty of murdering the Mongolian national in 2006 - had attempted to blackmail Najib.

The 101 East interview with Najib would be aired at 11.30am tomorrow (Oct 27) followed by repeats on Monday and Tuesday.

Viewers can watch the programme online after the first broadcast.

Meanwhile, Najib later apologised for losing his cool, stating he was concerned about his wife and sons, Norashman and Riza Aziz, being questioned by the police.

“I wish to thank Al Jazeera for the interview and apologise if I had lost my cool. I will not hesitate to say yes should they want to interview me again,” he told Malaysiakini.
