Opposition parties have given a call for a nationwide bandh today to protest the government's reform measures announced last week. The government, taking some politically tough decisions had hiked the price of diesel by Rs. 5 per litre, capped the supply of subsidised liquefied petroleum gas (LPG) cylinders to six per household and cleared 51 per cent Foreign Direct Investment or FDI in multi-brand retail - reforms, which saw its biggest ally, Mamata Banerjee, pull out of the UPA.
