Changes to new laws on guaranteed minimum prices for farmers, a key trigger for their massive protests near Delhi, and the possibility of exempting Punjab, Haryana and Uttar Pradesh from the laws, are likely to be discussed by Prime Minister Narendra Modi's cabinet today. Sources say the government is discussing various options before taking a decision. One of the formulations being suggested is to exempt key states from the farm bills, including exempting Punjab, Haryana and Uttar Pradesh, and also assuring that the Minimum Support Price (MSP) mechanism will continue.
