What did Sonia Gandhi say to Mamata Banerjee on the Trinamool Congress' offer of an alliance in Goa? TMC's Pavan Varma offers his version of events. "In fact, I told P Chidambaram, on the authority of what I learnt in my own party about Sonia Gandhi's response to Mamata Banerjee… So, the ball was in the Congress' court. And we were waiting for a response to what could not but have been a concrete proposal, for the principals of the parties to have interacted on it," Mr Varma said.
