Cabinet minister Abdul Rahman Dahlan will not remain silent on the Taman Manggis, Penang land deal, despite cancellation of the debate with Penang Chief Lim Guan Eng.

He said he will work with whistleblowers to make more "exposes" and with state BN to go hold roadshows on the matter.

"What's the next step? With the help of concerned Penangites & whistleblowers from within the establishment, there will be more exposé!

"I will also join hands with Gerakan and Penang BN to do proper roadshows to explain the double scandals to Penang people," he tweeted.

The debate scheduled to be televised live on TV3 next Tuesday was canned after police said it would be prejudicial to ongoing investigation.

Police advised Abdul Rahman, who is BN strategic communications director, to submit all evidence he has to the authorities.

TV3 in a statement today said it will " postpone " the debate on advice of police and the Malaysian Anti-Corruption Commission (MACC).

Abdul Rahman said he is "utterly disappointed" but will heed police advice to provide all evidence.

He said his team has been working hard to uncover "irrefutable proof" of the "double scandal".

BN is accusing Lim of taking kickbacks in the form of a discounted purchase of a bungalow at Jalan Pinhorn, after selling state land at Taman Manggis to a related entity.

Lim denied wrongdoing and is cooperating with the MACC in its investigation.

He insisted to continue with the debate, despite police advice, and insinuated that Abdul Rahman was rescued by the police.

However, Abdul Rahman said he has debated many opposition leaders inside and outside the Dewan Rakyat with no issue.

"The reason 'to avoid prejudice' is somehow good news for Lim. After all, I'm not the one under investigation who might do self-incrimination," he quipped on Twitter.
