Senior BJP leader L K Advani on Wednesday took on PM Manmohan Singh,asking him to reply to the Supreme Court poser on the alleged 2G spectrum scam. I have not come across any example of any Indian PM getting such a poser from the apex court. UPA sat on the answer for 11 months,now even 11 hours should not be lost in giving an answer to the SC, he said at the Patna airport and at an election rally in Sasaram.
