On the petrol price hike, Singh said the BJP-led NDA government in 2002 had decided to free the petroleum products from the state control so that the international price governs it and the current government is just continuing the policy of NDA.
The UPA government hasn't freed cooking gas, diesel and kerosene from the state's control keeping in mind the poor, he said adding that subsidiary was being given on these petroleum products.
On Congress president Sonia Gandhi's invitation to AIADMK chief J Jayalalitha for a tea party, Singh said it was just a courtesy gesture and too much should not be read into it.
