Rajya Sabha MP Naresh Gujral today said farmers across the country, especially in Punjab, suffered a setback due to the decision of the Union government to withdraw incentives given under a scheme for export of skimmed milk, ghee and other dairy products. The Union government had extended the incentive schemes by a year on April 11, but then decided to withdraw it within a week of its announcement with an objective to bring down the domestic prices, Gujral said.
