As many as 81 legislations have been lined up by the United Progressive Alliance government for the Winter Session of Parliament beginning on Thursday. However, with only 23 working days till the Lok Sabha winds up on December 21, the fate of several such legislations remains doubtful.The government will also push for the passage of six of the ten Bills pending in the Lok Sabha and 13 of the 36 Bills pending in the Rajya Sabha.
