The state-owned National Food Authority will sell at least 370,000 tons of ageing kernels from its warehouses at about 20 pesos ($0.36) a kilogram, about half of current market prices, Agriculture Secretary Francisco Tiu Laurel Jnr said at a press conference on Tuesday. The government wants to start subsidised sales this week, but may have to wait until after the May 12 vote depending on a ruling from the Commission on Elections, Laurel said.
