Only one of three witnesses turned up Friday as trial began in the 2G spectrum allocation case before a special court after formal charges were framed against all 17 accused, including former communications minister A. Raja and DMK MP Kanimozhi.

Though three witnesses were supposed to appear before the Central Bureau of Investigation's (CBI) Special Judge O.P. Saini, only Anand Subramaniam, presently working as the vice-president, Reliance Group, showed up as proceedings began.
