Even as chief minister B S Yeddyurappa has decided to take his fight with his bete noire HD Kumaraswamy to the Dharmasthala temple, Congress leader Siddaramaiah is all set to fire a fresh salvo against the CM, threatening to expose income tax irregularities involving Yeddyurappa and his family.

Siddaramaiah on Sunday alleged that Yeddyurappa and his family members had evaded income tax to the tune of Rs 339.54 crore and said that he would come out with details in Bangalore on Monday.

At a press meet here, Siddaramaiah described the tax evasion as the latest in the series of scams and scandals involving Yeddyurappa and his family members.

Referring to the face-off between Kumaraswamy and Yeddyurappa, the Congress leader condemned the duo for the swearing farce.

"The CM is degrading the Constitution by openly challenging Kumaraswamy to swear before God in Dharmasthala. It is apparent that both the leaders have no faith in the Constitution.

When we take the oath of office, we affirm our faith in Constitution. Then we should stick to it and have respect for the Constitution," he said, adding that he or any other Congress leader never indulged in such gimmicks.

Referring to the Centre's rejection of the governor's proposal to dismiss Yeddyurappa government on earlier occasions, Siddaramaiah said that does not mean that the governor should not send any report or recommendation to the Centre.

The Centre does not want to violate the Constitution and this is the reason why it is cautious on invoking article 356 to dismiss BJP government in Karnataka," he said.
