The opposition Grand Alliance in Bihar on Saturday organised a human chain across the state to express solidarity with the farmers agitating against the farm laws. "All the opposition parties including (Rashtriya Janata DalRJD), Left parties and Congress are forming human chains at even Panchayat and village levels. The aim is to support the farmers protesting against the black farm laws which only benefit the corporates. These laws will give farmers' land in private hands," said RJD leader Tejashwi Yadav.
