The Congress on Tuesday accused the BJP-led Centre of vendetta politics and said the opposition would not be cowed down by actions like the CBI raid conducted on the residences of former Union Minister P. Chidambaram and his son Karti Chidambaram."The truth is that revenge has become a DNA of the BJP. Neither Chidambaram nor any Congress leader or any other leader of opposition will be deterred, would be cowed down or would fear the politics of revenge and vendetta," Randeep Surjewala said, addressing the media over the "failures" of the Narendra Modi government in the last three years.Surjewala said the BJP and Prime Minister Narendra Modi had failed to take action against its leaders such as Madhya Pradesh Chief Minister Shivraj Singh Chouhan in the Vyapam scam, and Rajasthan Chief Minister Vasundhara Raje and External Affairs Minister Sushma Swaraj, who allegedly helped former cricket administrator Lalit Modi leave the country."The entire landscape of BJP is mired by one scam after another. If yardstick is morality then why is he (Modi) shying away from ordering an inquiry into the Sahara-Birla Computer Excel sheets, in which none other but the Prime Minister himself has been named repeatedly about having taken bribe," Surjewala said. The CBI (Central Bureau of Investigation) raided more than a dozen places on Tuesday morning in connection with Foreign Investment Promotion Board (FIPB) clearances given to INX Media (now called 9X Media) when it was run by Peter and Indrani Mukherjea, and Chidambaram was the Finance Minister.
