Differences within the government over the proposal for a National Investment Board appear to have miffed senior bureaucrats on Raisina Hill, as well. The proposal, said one of them, may have been forwarded by Finance Minister P Chidambaram, but it was discussed and approved at an elaborate Planning Commission meeting last month. So, the subsequent objection to it by some Cabinet ministers was inexplicable. The Cabinet is like a corporate board, he added, so it is unlikely that the proposal would have been unilaterally forced through without support from the top.
