The winter session of Parliament remains in deep freeze as the opposition continues to stall both the houses demanding Prime Minister's Narendra Modi's presence and when he is present, his apology for the lives lost due to demonetisation- related incidents. It is a month since PM Modi announced the government's decision to ban old Rs 500 and Rs 1,000 banknotes. Day 16 was marked with BJP leader LK Advani's strong disapproval of the way Lok Sabha was continuously stalled and the speaker and Parliamentary affairs minister Ananth Kumar were rendered powerless.
