The winter session of Parliament is set to start off on a stormy note with the Opposition set to raise the 'intolerance' issue and press for a resolution to condemn it even as Prime Minister Narendra Modi said the House should run meaningfully and constructively. Key reform bills like Goods and Services Tax bill are at stake this session. The winter session, which ends on December 23, will have 38 legislative items including seven new bills for introduction during its 20 sittings spread across 28 days.
