Prime Minister Narendra Modi took a sharp dig at Bengal Chief Minister Mamata Banerjee today as he raised the poll pitch ahead of the eight-phased assembly elections in the state. The Prime Minister used the Trinamool Congress's election slogan - "Khela Hobe (game on)" - and took a swipe at the ruling party. "Didi says Khela Hobe. BJP says - Chakri hobe (there should be jobs), Vikas hobe (there should be development), hospital hobe, school hobe (there should be hospitals and schools), Sonar Bangla hobe (and a golden Bengal)," PM Modi said in Purulia.
