Hours after West Bengal Chief Minister Mamata Banerjee got injured after an alleged attack on her by 3-4 men and terming it a planned conspiracy, an eyewitness stated her car rammed into a pillar. Mamata Banerjee, who got injured during her campaign trail in Nandigram today, has been hospitalised at the state-run SSKM Hospital in Kolkata. Meanwhile, the Bharatiya Janata Party has termed Mamata Banerjee's allegations of attack as a "political drama" orchestrated to gain sympathy ahead of the state assembly polls.
