Senior Congress leader P Chidambaram Tuesday blamed the NDA government for rise in petrol and diesel prices, saying it was happening due to "excessive taxes".

In a series of tweets, the former finance minister also demanded that petrol and diesel be brought under the GST immediately. "Relentless rise in prices of petrol and diesel is not inevitable. Because, the price is built up by excessive taxes on petrol and diesel. If taxes are cut, prices will decline significantly," he said.
