Encroachment by a particular class will cause grief: Madhya Pradesh minister Usha Thakur

"We have to uproot from the grassroots, the conspiracies cooked in different places since Independence. It is my humble prayer that you should not shed tears while just watching 'Kashmir Files', but keep an eye on whether such a 'file' is being created in your areas, your streets," Thakur said at the 29th foundation day of Laghu Udyog Bharti.
