Grand Alliance leaders on Wednesday slammed the campaigning style of Prime Minister Narendra Modi and accused him of raising non-issues.

The leaders of the Grand Alliance, which included JDU Rajya Sabha member Pavan Kumar Varma, RJD national spokesperson Manoj Jha and Congress leader Chandan Yadav, predicted a defeat for the BJP-led NDA and claimed the Grand Alliance would form the next government in Bihar.

Citing the example of Modi raising the issue of chief minister Nitish Kumar meeting a tantrik (sorcerer), Varma said: "It was an old video of Nitishji and he had explained under what circumstances the meeting had taken place. There was no relevance of that video."

BJP leader and Union minister Giriraj Singh had released the video in which Nitish was seen purportedly meeting a tantrik who not only hugged and kissed the chief minister, but also raised anti-Lalu slogans. Nitish had later clarified at a news meet that he had met the tantrik in June 2014 and there was nothing wrong in it.

Modi had continuously raised the issue during his public meetings and repeatedly mocked Nitish stating that the Grand Alliance comprised four members, which included the tantrik apart from the JDU, RJD, and Congress.

The tantrik was later identified as Baba Birnath Aghori, a resident of Siwan district.

The Grand Alliance leaders also attacked the Prime Minister Lalu Prasad's eldest daughter Misa Bharti bechari (helpless) and saying that Lalu had tried "set her up" in the Lok Sabha.

"The kind of language the Prime Minister had used against Misa Bharti was an insult to the women of Bihar. Narendra Modi had completely forgotten the dignity of the PM's post," stressed Varma.

Varma went on to add that it was probably for the first time that a Prime Minister had identified himself by his caste. "He claimed himself as an OBC and later went on to claim himself as a person belonging from the EBC category. You should not be surprised if he calls himself a Dalit leader while addressing a rally elsewhere," Varma quipped.

Manoj Jha of the RJD said: "There is a phrase in English - emperor without clothes. In terms of the language the BJP leaders have been using, all of them are without clothes."

Congress leader Chandan Yadav said: "Televisions cannot make a leader successful unless the person has a vision."
