A sumpah laknat is an oath, beseeching God to curse those who are in the wrong, and former prime minister Najib Abdul Razak has announced that he is willing to do just that this Friday to deny the allegations made against him by convicted killer Azilah Hadri.
Najib tweeted that he will be swearing the oath at Masjid Jamek in Kampung Baru, Kuala Lumpur.
Azilah, in a statutory declaration, claimed that the order to kill Mongolian national Altantuya Shaariibuu in 2006 had come from Najib, who was the deputy prime minister at the time.
Najib has denied Azilah's allegations, describing it as a complete fabrication and political plot to silence him.
