Karnataka Chief Minister and JD(S) leader H D Kumaraswamy has come under mounting pressure from the ruling coalition partner Congress to roll back the hike in petrol and diesel prices announced in the budget last week.

A day ahead of Kumaraswamy's reply to the debate on the budget in the Assembly on Thursday, senior Congress leader  Siddaramaiah said he had written to the chief minister to withdraw the hikes as it would affect the common man.
