Senior Congress leader Mallikarjun Kharge has resigned as the Leader of Opposition in Rajya Sabha, sources said on Saturday, a day after he filed his nomination papers for the All India Congress Committee president's election.
Kharge's resignation, which the 80-year-old leader sent to Congress president Sonia Gandhi on Friday night, is in line with the party's declared 'One person, One post' principle that was announced at the Udaipur 'Chintan Shivir' in May.
Senior leaders P Chidambaram, Digvijaya Singh and Pramod Tiwari are learnt to be the front-runners to take on the mantle of Leader of Opposition in Rajya Sabha.
The stage was set on Friday for a contest between Kharge and Shashi Tharoor for the Congress president's post. Kharge, a Dalit leader from Karnataka, has emerged as the clear favourite.
The nomination of K N Tripathi, a former Jharkhand minister, has been rejected.
Kharge, Tharoor and Tripathi filed nominations on the last day of the process which saw the AICC headquarters come back to life after a long time, with workers swarming the complex.
Kharge, flanked by top Congress leaders, had filed 14 sets of nomination papers with the proposers including Ashok Gehlot, Digvijaya Singh, A K Antony, Ambika Soni, Mukul Wasnik and members from the G-23 ginger group comprising Anand Sharma, Bhupinder Hooda, Prithviraj Chavan and Manish Tewari.
