The Karnataka leadership tussle within the Congress has intensified once again as senior leader Satish Jarkiholi hinted that a final decision on the Siddaramaiah vs DK Shivakumar power struggle could soon be taken in Delhi. Reports suggest top Congress leaders may be called by the high command to settle the issue and discuss a possible cabinet reshuffle. Meanwhile, fresh political speculation erupted after former minister KN Rajanna suggested Home Minister G Parameshwara could emerge as Chief Minister if Siddaramaiah does not continue in the post.
