The entire Cong leadership in the state was wiped out in a Maoist attack in May
The entire frontline of the Congress leadership in the state was wiped out in a May 25 Maoist attack on a party convoy.
Former state unit chief Nand Kumar Patel along with his son Dinesh, senior leader Mahendra Karma and former MLA Uday Mudaliyar were killed as the party convey was returning from a "Parivartan Yatra" (procession for transformation) at Darbha Ghati.
