Chhattisgarh Chief Minister Raman Singh has denied the allegations of Swaraj Abhiyan leaders that his Government had illegally purchased an AgustaWestland helicopter. In a press conference at Raipur last night, Mr. Singh said, the allegations levelled by former AAP leader Prashant Bhushan are baseless and politically motivated. Stressing that the deal was done through a global tendering process, Chief Minister said, the charges against a BJP-ruled state was an attempt to dilute the issue.<br/>Earlier yesterday, Swaraj Abhiyan leaders Prashant Bhushan and Yogendra Yadav in Delhi had accused the Raman Singh government of paying 1.57 million dollars commission to a company registered in tax-haven British Virginia Islands to procure the chopper.
