New Delhi, July 11 -- Amid intense speculation about his removal, Karnataka chief minister Siddaramaiah announced on Thursday that there is "no vacancy" for the CM's post. To buttress his claim, he added that Karnataka deputy CM DK Sivakumar- a claimant for the top post- also believes this. "As far as party is concerned, there is no question of changing the leadership. The question doesn't arise at all. I am elected for the full term," Siddaramaiah said. "That is what DK Shivakumar said, and I am also saying it... there is no vacancy (for CM). I am pretty much here before you. I am the Chief Minister of Karnataka," Siddaramaiah told the media. Both the CM and the deputy CM have camped in Delhi after the Congress general secretary in-charge of Karnataka Randeep Surjewala went to Bengaluru to hold a series of meetings with party MLAs, MLCs, MPs and senior leaders, fueling speculations that a change of guard in the state was imminent. Siddaramaiah's comment came even as he waited for an appointment with Lok Sabha's Leader of the Opposition Rahul Gandhi. Two senior Congress leaders said replacing Siddaramaiah with DK Sivakumar would be a "major political gamble" by the Congress party. "Out of the three Congress CMs, Siddaramaiah is the only OBC face. Both Revanth Reddy and Sukhwinder Sukhu belong to upper caste. When Rahul Gandhi has changed the general direction of the party towards OBCs, SCs and STs, can the Congress afford to drop Siddaramaiah?" asked one of them, a senior Congress leader based in Bengaluru....
