"If by obstructing Parliament, resoruces of the exchequer are filled, BJP will not hesitate...," he told reporters here, adding the party also cannot remain silent to "monumental corruption" witnessed during Congress-led UPA government.
Rudy termed tomorrow's reshuffle of Union Council of Ministers, Rudy as an "exercise in vain" and said the Manmohan Singh government, from which Trinamool Congress has pulled out, "should have sought a "fresh mandate" before going into this exercise (reshuffle)".
"After TMC's withdrawal...government lost its credibility. BJP feels this (reshuffle) is an exercise in vain," Rudy said.
The Prime Minister also came under sharp attack from the BJP leader who said Singh was known as an economist and for his honesty but in UPA-II that has "changed".
Rudy also said the PM was a Cambridge Unversity scholar, had served in prestigious positions, including Finance Minister, Finance Secretary, Governor of RBI etc and "nowhere in the world do we have a Prime Minister who is so qualified".
"But after promising growth rate of 9.2%, it is hovering around 5.2%", he added.
