PKR vice-president Rafizi Ramli said his lawyers will serve a letter of demand against blogger Raja Petra Kamaruddin over an allegedly defamatory article written by Raja Petra.

Rafizi said that although public records showed that Raja Petra was a bankrupt since 2001, legal action was necessary to uphold the truth.

"If I succeed (in my suit), I will not be able to claim anything. In fact, I will still have to pay legal fees.

"What is I seek is not money. I just want the truth," Rafizi said in a statement today.

The article in question was published on April 7 on Raja Petra's Malaysia Today blog, in which he alleged that businessman John Soh Chee Wen had given RM20 million to Rafizi and PKR secretary-general Saifuddin Nasution.

Rafizi said that this allegation was untrue, and that several PAS leaders have been parroting Raja Petra's claim of late in response to his statutory declaration on SRC International Sdn Bhd's funds being channelled to former PAS deputy president Nasharudin Mat Isa.

He said Malaysians must not let Raja Petra get away with making such claims.

Rafizi said that should there be no response to his legal letter, his lawyers have been instructed to file a suit against Raja Petra.

"Although he is bankrupt, I want to see him brought back one day to answer all the allegations against him, including my defamation suit.

"This is the first time I've sued anyone. (I'm doing this) because I know who is behind Raja Petra," he said, while urging friends and foes alike to be wary of mercenary political writers.

Malaysiakini is attempting to reach Raja Petra for comments.
