Congress leader Siddaramaiah on Tuesday attacked Karnataka Chief Minister B S Yediyurappa on the issue of taking banking exams in the local language and went on to compare him with a mouse.

In a series of tweets, Siddaramaiah demanded the resignation of the Karnataka CM and said, “BSY's followers call him Huli (Tiger) but in reality he is ili (Mouse). He hides in burrows when he has to stand up in front of Narendra Modi. Let him resign if he cannot ensure justice to Kannadigas.”

The former Karnataka chief minister had previously compared Yediyurappa to a dog.
