The Congress in Karnataka has a new chief - DK Shivakumar, the party's high-profile troubleshooter in the state. The seven-time MLA formally took charge as the president of the state unit, KPCC, on Thursday morning at a virtual rally for which the BJP-ruled state government had denied permission thrice. Congress President Sonia Gandhi sent a letter appreciating the efforts made to hold the event in keeping with COVID-19 guidelines and commended the use of technology to avoid crowding. Congress leaders Rahul Gandhi and Priyanka Gandhi Vadra also called to wish him well.
