Senior BJP leader M Venkaiah Naidu today alleged that the script to destabilise of the Karnataka government was written in New Delhi and was being implemented at Bangalore Raj Bhavan through the governor.

Reiterating party's demand of recalling Karnataka governor H R Bhardwaj immediately, he said that there was a need to hold a national level debate on the role and functioning of the governors.

Addressing a press conference here, Naidu said the Karnataka governor was virtually acting as an opposition leader.

The BJP leader alleged that Bhardwaj played a partisan role and made a mockery of the institution and tried to destabilise the elected Karnataka government from the day he took charge.

"Bhardwaj must immediately tender his resignation for his undemocratic action," the BJP leader said. He said that the BJP core committee would soon meet to plan agitation if the Centre failed to recall Bhardwaj.

Naidu alleged that Bhardwaj embarked upon a political confrontation with the elected government and virtually converted the Raj Bhavan into the epicentre of political conspiracy to destablise the state government.

"The Rajbhavan in Bangalore has become a centre for political activity and hatching conspiracies," he said.

"Even after Chief Minister Yeddyurappa proved his majority last time, the governor, as per his game plan, hastily recommended to the Centre for action under article 356 of the constitution," he added.

Naidu said that Congress was behind the conspiracy that was trying to destablise the elected non-Congress government through the governor. He added that such a behaviour of the governor puts at stake the federal fabric of the country which was one of the foundation stones laid by our founding fathers.

"The role and functioning of the governor in the federal polity of India have time and again been creating constroversies," he said adding that, "After the latest action of the Karnataka governor, the dignity and the prestige of the office of the governor has suffered a great deal."

"The governor's actions and loose comments from time to time were clear indications of his mission. The Karnataka governor had declared that he is a Congress man and feels proud to be so even after occupying the gubernatorial post," he said.

The former BJP President said that there was a need to have a national debate on the role, appointment, behaviour and responsibility of the governor.

He alleged that the UPA government has disregarded the Sarkaria Committee recommendations and also the constitutional review commission presided by justice M N Venkatachaliah.

"Justice Venkatachalaiah committee has clearly recommended that people who are not actively engaged in politics should be selected as governors," he said.

Former Union Minister Bandaru Dattatreya and state party President G Kishan Reddy and other leaders were present at the press conference.
