Questioning Ms. Banerjee's "anger", he said "every day, she crosses the Laxman Rekha and uses the choicest adjectives against Narendra Modi."

The BJP on Saturday lashed out at West Bengal Chief Minister Mamata Banerjee for her rhetoric against the party’s prime ministerial candidate Narendra Modi and for failing to translate her “poribortan” (change) into good governance.

Senior BJP leader Arun Jaitley, in a statement, questioned Ms. Banerjee’s “anger” and said: “Conventional wisdom would suggest that Mamata Banerjee’s and her party’s traditional rival in West Bengal are the Left parties. The Congress Party would occupy the third spot with the BJP being an also ran. Why then is the BJP the principal target of Didi’s attack? Every day, she crosses the Laxman Rekha and uses the choicest adjectives against Narendra Modi.”

Questioning her leadership, Mr. Jaitely said good governance has not been her forte and “angry and agitational politics” is her strength. 

“The Bhadralok had all shifted to Didi [Ms. Bannerjee] as a reaction. It is this very vote which now wants to see Narendra Modi as the Prime Minister. Didi’s Poribortan is not good governance or development. It is anarchy, booth capturing and encouragement to illegal infiltration,” he said.

The BJP, which is riding high on the Modi-wave and expecting to cross the 272+ mark, is confident of a good-show in West Bengal. “The West Bengal results for 2014 may produce a surprise. Next only to Uttar Pradesh, the BJP’s vote share is expected to rise in West Bengal,” Mr. Jaitley said. 

He went to say that Ms. Banerjee is worried because she fears the “radical shift of 15 per cent vote share that put her in power in the Assembly elections, to the BJP.”

“It is the last of these votes which is Didi’s mainstay. For this cause, she has to justify infiltration and abuse Modi. The more she does that, the more she alienates herself from a significant section which put her in power. How long can Didi rely on the illegally imported vote? Even if she manages to retain a large number of seats this time, warning signals for the Assembly elections are beginning to be heard,” he said.
