Why is Samajwadi leader Amar Singh in tension? This time it's not because a channel istargeting his friend Amitabh Bachchan but because the Samajwadi Party leader has beenserved a notice from the Department of Excise for having served liquor at a lavish partyhe organised on January 26, 2001. And guess who was the star attraction of the show? Well,besides Amitabh Bachchan and the routine lineup from Mumbai, the list also included the PrimeMinister's foster son-in-law Ranjan Bhattacharya, who came with his family and stayed late. Singh, last heard, was wondering how to handle the crisis.
