Domestic cooking gas LPG price on Wednesday was increased by Rs 25 per cylinder - the second straight month of increase in rates. Subsidised LPG now costs Rs 859 per 14.2-kg cylinder in Delhi, according to a price notification of oil companies. This is the second straight month of a price increase. Rates were hiked by Rs 25.50 per cylinder on July 1.Non-subsidised LPG rates were increased on August 1 by the same proportion, and now the subsidised cooking gas prices have been raised.There is hardly any difference in the rate of subsidised and non-subsidised cooking gas. Industry sources said the subsidised LPG price was not raised on August 1 because Parliament was in session and the government could have been attacked by the opposition.
