West Bengal Chief Minister Mamata Banerjee on Saturday alleged that the Election Commission of India chalked out seven-phase polls to enable Prime Minister Narendra Modi and his cabinet colleagues to carry out extensive campaigning using the nation’s resources. Addressing a public meeting at Gajol in Malda district in support of Maldaha Uttar TMC candidate Prasun Banerjee, a former IPS officer, Mamata Banerjee, the party supremo, said polls have been scheduled from April 19 to June 1 so that Modi and his cabinet colleagues can travel on special planes across the country before every phase to “overwhelm the Opposition”.
