Penang Chief Minister Lim Guan Eng should consider his options on the investigation against him, including going on leave, former Bar Council president Ambiga Sreenevasan said today.

"He should consider his options. The good thing is that he has urged the Malaysian Anti-Corruption Commission (MACC) to investigate quickly and I would echo that, because this is something that can be investigated quickly," Ambiga told Malaysiakini .
