Agricultural union leaders on Sunday announced that they will observe a day-long relay hunger strike on Monday at every site of protest as part of their ongoing agitation against the three new farm laws of the Centre. Farmers will also halt toll collection on Haryana highways from December 25 to 27, the leaders said. Thousands of farmers, mainly from Punjab and Haryana, are protesting against the laws for the last over four weeks at various border points of Delhi and demanding that the legislations be rolled back. “Farmers will begin a day-long relay hunger strike on Monday at all sites of protest against the new agri laws. It will be started by a team of 11 members at protests sites here,” Swaraj India chief Yogendra Yadav said during a press conference on Sunday at the Singhu border.
