Ahead of a key meeting to resolve the deadlock over the JPC issue, Government today questioned the logic behind the Opposition's demand saying it will only lead to duplication of probe into the 2G Spectrum scam. Leader of the House and Finance Minister Pranab Mukherjee sought to drive home this point at a meeting of Independent MPs and single member parties convened by Speaker Meira Kumar as part of her efforts to break the impasse in Parliament. He said that CBI, Enforcement Directorate (ED) and the Public Accounts Committee (PAC) are already looking into the issue. The Speaker told reporters after the meeting that the members expressed their views very categorically and wanted the House to function.
