Prime Minister Narendra Modi today declared that migrants will not be required to submit ration cards or address proof to get cooking gas where they are working. A self-declaration as a "proof of address" will suffice, he said at the launch the Ujjwala 2.0 scheme for free cooking gas from Uttar Pradesh, where assembly polls are due next year. The politically crucial state -- seen as the gateway to Delhi -- is set to have its assembly polls next year, in which the Yogi Adityanath government is seeking a second term.
