MCA deputy president Wee Ka Siong has been urged to name the corrupt official allegedly linked to the Penang undersea tunnel project, which has hogged headlines since January.

At a press conference in Komtar yesterday, Penang Chief Minister Lim Guan Eng said although Wee had launched another personal attack against him, the BN leader failed to prove there is corruption involved in the RM6.3 billion project.

"It is always when you cannot prove your case that you make personal attacks. I challenge Wee to state the name of the Penang government leader who is corrupt and complicit in the corrupt act with the contractor awarded the project in 2013," Lim said.
