AFTER luxury goods like petrol and LPG, its the turn of the common mans staple dietwheat. While ration shop prices have remained steady for almost three years now, market prices of wheat and wheat products like atta, maida, sooji and bread/cake are soaring. From Rs 6-7 per kg three months ago, atta is now ruling at Rs 9-10 and a pound of bread now costs Rs 6-8. More important is the question: Is this the end of the price spiral, or will atta and bread become dearer still? "Were really worried about the rise in food prices, especially wheat prices which have gone up by more than 25 per cent," admits Y.K. Alagh, Minister for Planning.
