Congress General Secretary Digvijay Singh courted another controversy by saying he did not rule out the involvement of Sangh in Mumbai serial blasts,evoking sharp criticism and condemnation from BJP. Even as various intelligence agencies are yet to get a breakthrough in the Mumbai blasts,Singh did not rule out the involvement of the Sangh in the bombings. "I do not rule out anything. If they want evidence about Sangh's involvement in terror activity,I have got evidence. But not in this case," Singh told the media. Reacting sharply to the Congress leader's comments,the BJP termed them as 'disgusting and objectionable' and sought an apology from Congress president Sonia Gandhi for what Singh had said. Senior BJP leader Ravi Shankar Prasad charged the Congress leader with trying to destabilise the nation by making such statements,while his colleague Shahnawaz Hussain accused him of trying to divert the course of investigations into the Mumbai blasts and politicking on a sensitive issue like terrorism and dead bodies. "The BJP strongly condemns the disgusting statements of Digvijay Singh and seeks an apology from Congress chief Sonia Gandhi on this," party spokesman Shahnawaz Hussain told reporters here. "While the threat of terrorism is looming large over the whole nation and people need to be balmed after being hurt by the shock of Mumbai blasts,Digvijay Singh is playing politics over terror and dead bodies. He is trying to divert the course of investigations into the Mumbai terror attack by making such statements." Congress cautious on Digvijay's remarks Congress on Saturday chose to be cautious on party General Secretary Digvijay Singh's controversial statement that he did not rule out the involvement of Sangh in Mumbai serial blasts. "Ït is the job of the investigating agencies to decide whom to include and whom to exclude" in the probe,party spokesman Shakeel Ahmed told reporters while reacting to Singh's statement which drew sharp criticism from BJP. Ahmed downplayed the controversy arising out of Maharashtra Chief Minister's statement that NCP,Congress' ally in the state,should not have been given the Home portfolio. The Chief Minister has clarified that he has been quoted out of context and there is "no misunderstanding" now on the issue. The Congress spokesman took a dig at Gujarat Chief Minister Narendra Modi for his statement that had Sardar Vallabhbhai Patel been alive innocent people would not have lost their lives due to terrorist activities. "If Sardar Patel had been alive,then there would not have been the leadership of L K Advani and Modi nor there would have been communal terrorism",he remarked.
