As the war of words between Rosmah Mansor's aide and a DAP assemblyperson continues, Penang Chief Minister Lim Guan Eng is becoming collateral damage.

Yesterday, Rizal Mansor roped Lim into the row to drive home his point on Rosmah's educational background that made her suitable for her Permata post and asked if the chief minister had the required expertise to helm the Penang Water Supply Corporation.

In his latest retort, Rizal once again mentioned Lim, raising the latter's corruption case.

“Is there not a single DAP assemblyperson in Penang who is qualified to be made chief minister to replace Lim, who has been charged over allegations of corruption?

“Is this not an insult to DAP assemblypersons?” he asked.
