PKR vice-president Rafizi Ramli has yet to hear from the lawyers representing Prime Minister Najib Abdul Razak and his wife Rosmah Mansor.

Contacted today, he said that since it is the year end, everyone could be on holidays.

However, the Pandan lawmaker saw no alternative for Najib and Rosmah apart from suing him.

"I don't think they would back down, which is a good thing. I don't see how they could back down," he told Malaysiakini .

Furthermore, Rafizi said the letter of demand had stated that he should apologise within 14 days.

"Perhaps they are waiting to see if I would change my mind," he added with laughter.

On a serious note, the Pandan lawmaker said that he would not reconsider and was prepared to face the prime minister and his wife in court.

Last week, Rafizi responded via his lawyers that he would defend his statements in court, arguing that his remarks were justified and fair.    

On Dec 4, Najib and Rosmah slapped the PKR leader with a legal threat over his speech on Nov 23, where he talked about fuel subsidies and diamond rings being purchased for Rosmah.

Rafizi had told the audience that each month the Umno government saved RM1 billion from the removal of subsidies, which could be used to purchase 20 expensive rings for Rosmah, each costing RM20 million.

Najib and Rosmah’s lawyers stated that the allegations against the couple were "baseless and false", made with the "primary intention of attacking and damaging" their reputation for no justifiable reason.

It also added that the allegations had caused the couple great distress and embarrassment.

After receiving the letter of demand, the Pandan MP said he was looking forward in going to court as his lawyers were eager to grill Rosmah.

Furthermore, he added that the "ring had been a source of intrigue for years".
