Maharashtra Chief Minister Prithviraj Chavan opposing Prime Minister Narendra Modi's decision to do away with the Planning Commission and to have a new institution in its place said it will "cost the nation". Mr.Chavan tweeted on Tuesday that it is dangerous to hand over financial matters to the Free Economy. Chavan's comments came after Modi tweeted that the government wants ideas from the people on how the new institution which will replace Planning Commission will look. The Prime Minister, in his Independence Day speech, had said that his government would scrap the six-decade old plan panel to set up a new think-tank that will be more federal in nature.
