KOLKATA: Narendra Modi government finally got a breather from Bengal chief minister Mamata Banerjee on GST. While addressing industrialists Mamata instructed her finance minister Dr Amit Mitra , who is incidentally the chairman of the empowered committee of state finance ministers on GST to ensure the passage of the bill this Monsoon session .Making her stand clear, she said , "I am politically opposed to the BJP government. But it doesn't mean I would block the passage for the pro- people bill. Why some parties are unnecessarily being politically vindictive and blocking the bill?" asked Banerjee.Speaking at an felicitation ceremony organised by the various Chambers of Commerce, Banerjee told Mitra: "GST is long pending. Within the next two meetings ensure its passage. Build a consensus and do it."
