A day after Home Minister Amit Shah left West Bengal, following his two-day high-voltage campaign in the state, election strategist Prashant Kishor on Monday claimed on Twitter that the BJP will struggle to cross the double-digit mark in assembly polls. Kishor, who has been roped in by TMC supremo Mamata Banerjee to strengthen her party's poll prospects, said that he would quit the microblogging site if the saffron party does any better than what he predicted.

"For all the hype amplified by a section of supportive media, in reality BJP will struggle to cross double digits in West Bengal," he tweeted. "Please save this tweet and if BJP does any better I must quit this space!" Kishore added.

The saffron party, which recently received a shot in the arm after political heavyweight Suvendu Adhikari, a TMC MP and nine MLAs joined its camp, has asserted that it would win over 200 seats in the upcoming polls.

BJP national general secretary Kailash Vijayvargiya, in response to Kishor's tweet, said the country would end up losing a poll strategist after Bengal elections.

"Given the ongoing BJP tsunami in Bengal; once the new government is formed, the country will have to lose an election strategist," Vijayvargiya quipped on Twitter.

Meanwhile, Union minister Ramdas Athawale expressed confidence that the BJP will win more than 200 seats in the forthcoming West Bengal Assembly elections and form the next government in that state. Talking to reporters here, Athawale, whose party is an ally of the BJP-led central government, also said he will seek four to five seats for his Republican Party of India(A) in the West Bengal polls.

He claimed Union Home Minister Amit Shah's recent visit to West Bengal has proved that the days of Chief Minister Mamata Banerjee's government are numbered. Assembly elections are likely to be held in West Bengal in April-May.
