The Karnataka cliffhanger just got a new twist with state party chief DK Shivakumar, one of the two contenders for the top post, sending his "best wishes" to his rival today. The 61-year-old, who was expected to visit Delhi this evening, in a sudden turnaround, said he would not and wished Siddaramaiah all the best. Mr Siddaramaiah, who is already in Delhi, is expected to meet party chief Mallikarjun Kharge. The Central observers, deployed by the Congress to sense the mood among the party MLAs, have submitted their report.
