Penang Chief Minister Lim Guan Eng expressed surprise that Selangor Menteri Besar Azmin Ali has "interfered" in the running of his administration.

Lim said this was the first time a menteri besar or chief minister of a Pakatan state had commented on another's administration.

"Out of respect, we usually do not do it. If there is any issue to discuss, we would raise it behind closed doors and not in public," Lim told reporters after attending the Penang Development Corporation's Chinese New Year open house do today.
