Prime Minister Najib Abdul Razak has indicated that he would seek to expunge former premier Dr Mahathir Mohamad's affidavit in support of former MCA president Dr Ling Liong Sik's application to strike out the PM's suit.

This comes as there are no signs of mediation to Najib's suit against the former transport minister.

Najib's lawyer Nur Emilia Mohd Izham said his client's application to expunge Mahathir's affidavit will have to be heard first.
