New Delhi: Team Anna has reiterated calls for probe into coal blocks allocations after then coal secretary told CNN-IBN that Prime Minister Manmohan Singh did not push for auctions. The Prime Minister's Office on Saturday ruled out a SIT probe into the coal block allegations as demanded by Team Anna, slamming it for questioning the Prime Minister's integrity, and calling Anna Hazare and his coterie 'anti-national'. In a strongly worded letter, Minister of State in the PMO Narayanasamy gave a point-by-point rebuttal of the allegations made by Team Anna against the PM in the case.
