The meeting, chaired by NDA chairperson and Bharatiya Janata Party (BJP) leader L.K. Advani at his residence, was attended by senior members of the alliance.
"I'm confident that ultimately our government will be safe... The governor is waiting, he wants to rule the state, he wants to rule Bangalore," senior BJP leader M. Venkaiah Naidu told reporters in Bangalore.
He lashed out against Bhardwaj and said: "He wants to murder democracy - we will not allow it."
"We will fight legally and politically, we are confident that success will be ours," said Naidu.
The Karnataka governor had sent a report to the centre Sunday, in which he has reportedly recommended president's rule in the state. The report followed the apex court verdict restoring the membership of 16 rebel legislators - 11 of the BJP and five independents.
The report was sent after 10 of 11 BJP legislators expressed "unconditional support" to Chief Minister B.S. Yeddyurappa.
Though Bhardwaj has not made public his report, Yeddyurappa -- apprehending dismissal of his government -- wrote to Patil late Sunday urging her to reject the "unconstitutional move" of Bhardwaj.
