Congress President Mrs Sonia Gandhi today backed Finance Minister Pranab Mukherjee on budget at Congress Parliamentary Party meeting. Mrs Gandhi has indicated there will be no roll back on fuel pricing. Mrs Gandhi said the Finance Minister has done a good balancing job. Finance Minister Pranab Mukherjee's budget proposals on petroleum products have led to an increase in fuel prices, triggering demands for a rollback even from a section of the Congress' allies in the government.<br/><br/>Prime Minister Dr Manmohan Singh has also ruled out a rollback in the hike of fuel prices.
