Congress MLA Pargat Singh today objected to the repeated installation of concrete barricades to stop farmers at the Punjab-Haryana border.Questioning the silence of Chief Minister Bhagwant Singh Mann on the issue, he asked whether a state government can erect concrete barricades to block the movement of people from another state in such a manner.Pargat said, “The BJP-led Haryana Government is once again barricading its inter-state borders with Punjab. The silence of Chief Minister Bhagwant Singh Mann is difficult to understand.”
