Senior Congress leader Priyanka Gandhi Vadra is pushing for a leadership change in Karnataka, sources told NDTV Tuesday afternoon, after lengthy meetings between party leaders and the squabbling duo of Chief Minister Siddaramaiah and his deputy, DK Shivakumar. Sources said the Congress is likely to change its chief minister to prevent another face-off between its top two leaders, which could be very damaging with an election due in 2028. Earlier today Congress leaders - including party boss Mallikarjun Kharge, MP Rahul Gandhi, and General Secretary KC Venugopal - met Siddaramaiah and DK Shivakumar, jointly and individually at the party's head office in Delhi this morning. After the meetings Gandhi and Venugopal left to brief veteran leader Sonia Gandhi on the discussions.
