The Union Cabinet today authorised the Prime Minister to give final nod to the President's address for the joint sitting of Parliament. Ms Pratibha Devisingh Patil will address on the opening day of Budget Session next Monday spelling out government's policies for the year and views on various topical issues. The Cabinet is also believed to have discussed the JPC demand of the opposition on the 2G issue. The stand-off between the government and the opposition on the JPC probe led to the washout of the entire Winter Session of Parliament. The issue is understood to have been discussed yesterday at the Congress Core Group meeting, chaired by party President Sonia Gandhi. Our correspondent reports, the Congress party is keen that such a probe covers the BJP-led NDA's stint in power and is claiming that the main opposition will have a lot to answer.
