NEW DELHI/ CHENNAI : Setting the stage for fresh hostilities, the Prime Minister's office on Saturday aggressively dismissed corruption allegations levelled by Team Anna against Prime Minister Manmohan Singh over coal block allegations for being devoid of evidence. Minister of state for PMO V Narayanasamy followed up a curt letter to Hazare with a fusillade against the Gandhian leader's associates Arvind Kejriwal and Kiran Bedi, calling them "anti-nationals" and alleging their financial dealings are not above board.
