As parliament begins its month-long session today, Prime Minister Narendra Modi emphasised the importance of clearing the landmark reform, the national Goods and Services Tax (GST), which the government wants to roll out on July 1. The PM said he seeks the opposition's cooperation and "a breakthrough on GST." This weekend, the Finance Minister said the measure is on track - but much will depend on how much the opposition cooperates - and that, in turn, will be influenced by the results that will be shared on Friday from five states, including Uttar Pradesh, that have just voted.
