PKR vice-president Rafizi Ramli is planning to expose what he terms as "another outrageous financial scandal" to hit the nation.

"Wait and see," the Pandan lawmaker tweeted, adding that he expected to be arrested again over this issue.

Responding to one user, who asked him if the new revelation concerned a "fund, company, cows, goats or ducks", Rafizi replied: "Ha3 (laughter) you tunggu (wait). But outrageous enough. I think people will be angry."

The PKR leader also joked about how despite being arrested frequently, he has failed to shed weight.

Rafizi said that he would write to renown ulama (religious scholars) around the world, provide them with the background of the scandal and request a fatwa (religious edict).

"It is time to issue a fatwa on corruption," he added.

To another user who asked him to let someone else release the details in order to avoid the heat, Rafizi, who is currently in London, cited two reasons to explain why this is not possible.

"Because (1) media may not cover it; issue of credibility, (2) they will come down hard on newbie (who exposes the scandal," he said.

Contacted later, Rafizi declined to elaborate on the scandal for now.

On a separate matter, the PKR leader also took a jibe at Gerakan Youth chief Tan Keng Liang, who is often critical of DAP and Penang Chief Minister Lim Guan Eng.

He said a campaign should be launched to persuade Gerakan to field Tan, whom he described as the party’s "hero No 1", to contest against Lim if a snap polls is called in Penang.
