Thousands of protesting farmers holding march with their tractors from the three protest sites outside Delhi in a ‘rehearsal’ of their January 26 parade while police have heightened security arrangements in the city. Farmers from Singhu, Tikri and Ghazipur borders started their tractor rally on Thursday morning in a rehearsal of the planned protest on Republic Day to further intensify the ongoing protest against the three farm reform laws. The tractor march comes a day ahead of another round of talks with the central government over the farm laws.
