Former prime minister Najib Abdul Razak jested that he must be a serial killer based on all the people he has been accused of having killed.

"(Someone told me) they used to believe that I killed Altantuya (Shaariibuu).

"Kevin Morais, (they say) I killed him, (P) Bala(subramaniam), I killed him.

"This must mean that I am a serial killer, I killed everyone," Najib said at a ceramah in Langkawi last night.

He added that these were among the great lies spread by Pakatan Harapan, which led to BN's downfall in the 14th general election.

Altantuya is a Mongolian national and former lover of Abdul Razak Baginda, a close confidante of Najib.

Her cousin Burmaa Oyunchimeg insisted that she has seen a photo of Altantuya, Razak Baginda and Najib together.

Najib denies having ever met Altantuya.
