Planning Commission deputy chairman Montek Singh Ahluwalia has said there is no case for a road regulator despite the promise made by Finance Minister P Chidambaram in the 2013-14 budget. Ahluwalia has made the comments in his reply to a proposal sent by the Ministry of Road Transport and Highways to set up the regulator. While he has acknowledged that investments are dragging in the sector, he has said those cannot be corrected by a regulator.
