She asserted that the BJP would not be able to win a single seat in Bengal including that of Darjeeling, which they won in 2009.
Earlier in the day, lashing out at the Trinamool Congress for claiming to be a do-gooder for Muslims, Narendra Modi said the minority community was far better-off in his state Gujarat than West Bengal.
"Muslims in West Bengal have to force the Trinamool Congress government to do politics of development for them instead of indulging in vote-bank politics," he said.
Raising the issue of Bangladeshi migrants who were allowed into the country for "vote-bank politics", Modi said they would have to go back, while refugees who have been thrown out of Bangladesh on religious grounds would be greeted with open arms.
"BJP's position is very clear, vote-bank politics has destroyed the country ... Those who are Bangladeshi infiltrators, will have to go back," he said.
