Bharatiya Janata Party (BJP) National General Secretary Kailash Vijayvargiya on Saturday said that the attempt by Trinamool Congress to create controversy has backfired as the district administration as well as Election Commission has called the incident in Nandigram that resulted in an injury to West Bengal Chief Minister Mamata Banerjee as an accident. "Reports of district administration and EC have called it an accident. Mamata ji has said that she was pushed. It's a controversy between governance and administration. This attempt of stirring controversy and gain sympathy has backfired," said Vijayvargiya after BJP's central election committee meeting in Delhi. "We are not worried. Those (TMC) who tried to use the wrong means to gain sympathy from people should be worried. They have been exposed," he added when asked if Banerjee's injury could swing voters in her favour.
