Referring to a top Intelligence Bureau (IB) official being quizzed by the CBI in connection to the Ishrat Jahan encounter case, Modi said the Centre has pitted the two investigative agencies against each other.
The CBI grilled IB Special Director Rajinder Kumar earlier this month over his alleged role in the conspiracy to stage a fake encounter in 2004 in which Ishrat and three others were killed.
Modi, the chief of the BJP's poll campaign committee for the 2014 Lok Sabha elections, said the UPA government has turned into a lethargic system, adding that formation of policies alone can not bring the desired results.
Addressing the gathering on the sidelines of a book releasing function here, Modi alleged that the National Advisory Council, set up by Congress chief Sonia Gandhi, was formed to put pressure on the Planning Commission.
The BJP leader arrived in Mumbai on Thursday, his first visit after taking over as the chief of the BJP's poll committee, met Shiv Sena chief Uddhav Thackeray at the latter's residence Matoshree.
The meeting was seen as an attempt by Modi to pacify the Sena chief, who had expressed his displeasure two days back in his party mouthpiece over Modi's 'Rambo' act of rescuing 15,000 Gujaratis from the flood-ravaged Uttarakhand. He, however, backtracked later, saying he was not against Modi but those who were propagating for him.
The meeting was also seen as an effort by the BJP nto ensure that it did not lose another ally after the exit of JD(U) earlier this month. The NDA has shrunk alarmingly and many in the saffron camp believe it would make the dream of coming back to power all the more difficult to achieve.
Modi, besides addressing industry honchos, also met Maharashtra BJP leaders and formulated strategy for the next parliamentary elections.
