Farmers' protest is set to intensify today as they plan to block Delhi-Jaipur highway, a day after one of the 32 protesting unions moved the Supreme Court against the centre's contentious agricultural laws. The farmers' leaders have dismissed claims that "ultra-left" and "pro-Left Wing Extremist" elements have hijacked their agitation, the biggest in the last few years. Thousands of cops are on duty at entry points to the national capital to block the movement of the protesters.
