Opposition Leader Anwar Ibrahim wants the prime minister to apologise and retract his statement that Anwar and Pakatan Rakyat offered now Foreign Minister Anifah Aman RM100 million to defect to Pakatan Rakyat.

PM Najib Abdul Razak made the statement at the Umno general assembly, but the claim by Anifah is now part of an ongoing defamation suit brought by Anwar.

"PM Najib made a scurrilous and slanderous attack upon Pakatan Rakyat and myself…," Anwar said in a statement today.

"Pakatan Rakyat has never practised and will never tolerate money politics or corruption.

"We will save this country by reasoned arguments and by the example of good governance in the states administered by us," he said.

Najib in his Umno general assembly winding up speech Sunday described the opposition as the "mother of all corruption" in relation to the Anifah case.

"They (the opposition) are the mother of all corruption. We are accused of all sorts things by the opposition.

"Don’t think we are bad, the opposition is even worse," the Umno president said, while showing delegates a copy of Utusan Malaysia ’s report on the case.

Najib said he checked with his lawyers and were told that it is not subjudice for him to raise the matter.

Anwar is suing Anifah for saying that Anwar and Pakatan Rakyat offered him the deputy prime minister post if he defected.

In his testimony, Anifah said the offer was made by businessman Ishak Ismail, who acted as an intermediary.

Ishak in a statement yesterday denied the claim and challenged Anifah to repeat the allegation outside of court so Ishak can take legal action.

Anwar had in 2008 announced that BN MPs will defect to Pakatan to form a new government but this did not happen.
