New Delhi, June 23: Congress general secretary Digvijay Singh has said that he stands by every word he said about Trinamool Congress chief Mamata Banerjee’s conduct in the run-up to the presidential election, despite the party distancing itself from his remarks. He had termed Banerjee’s behaviour as “immature” and “erratic” during the discussions on the July 19 presidential poll.  He said that Banerjee by naming Prime Minister Manmohan Singh as one of her choices for the president’s post was “certainly an embarrassment for the prime minister” and the party.  The Congress had earlier this week snubbed Digvijay Singh after his remarks concerning Banerjee.  “Digvijay Singh is not officially authorised to speak on behalf of the party,” a party statement said. In a television interview earlier, Digvijay Singh termed Banerjee’s revelation of the names of the Congress’s presidential contenders and her own suggesting three other names without the consent from these leaders as a mistake and “not a mature thing to do”. “She has been erratic in some way but let us also confess that she has been a great fighter all her life,” the Congress leader said.  (IANS)
