A protest rally was being organised at New Delhi's Jantar Mantar in the wake of AgustaWestland controversy.
Destabilising elected governments in states with a motive to capture power all over, the Bharatiya Janata Party (BJP) is "killing democracy", Congress president Sonia Gandhi said here on Friday.
"Their (BJP) lust for power is increasing and thus they are killing the democratically-elected governments forcefully," Sonia said, addressing the crowd at the Loktantra Bachao March here.
She said BJP was not concerned about the democracy as their only motive "is to capture power everywhere", adding Congress was a party that had "given their blood and laid down lives to protect the basic principles of humanity".
Congress and the BJP have been of late involved in a bitter banter on a range of issues, including the AgustaWestland VVIP chopper scam.
