Karnataka Chief Minister Siddaramaiah on Monday expressed visible anger when a group of reporters repeatedly questioned him about deputy Chief Minister D.K. Shivakumar potentially replacing him as the head of the state government, terming the speculation as media-driven. CM Siddaramaiah, responding to queries about leaders of the Bihari community in Bengaluru expressing a desire to see Shivakumar as the next Chief Minister, retorted sharply, asking the reporter if there was no other subject to discuss.
