Responding to Rizal Mansor's challenge to sue him for defamation, Dr Mahathir Mohamad's lawyer said he will do so exactly a week after Prime Minister Najib Abdul Razak hauls the Wall Street Journal to court.

Mohd Hanif Khathri Abdullah also told the aide to the prime minister's wife Rosmah Mansor that there is a struggle which is far greater than him.

“This is to defeat Najib, Rizal's 'boss'. Rizal is not a relevant factor in the mission to save Malaysia."
