Amid speculations over the chief ministerial face in Karnataka after Congress’ emphatic victory in the Assembly polls, state party president DK Shivakumar on Sunday said that he has no differences with Siddaramaiah, who is being seen as a front-runner for the position of the top post. “Some people said that I have differences with Siddaramaiah. There are no differences between us,” said DK Shivkumar while addressing a press conference in Tumkur on Sunday. The Karnataka Congress chief’s remarks came hours after posters were put up by the respective supporters of both leaders referring to them as the “next CM” of Karnataka. “Many times I have sacrificed for the party. I sacrificed and helped and stood with Siddaramaiah. Wasn’t I patient when I was not made a minister in the beginning? I have given cooperation to Siddaramaiah,” he said.
