The 'Tractor March' of Jai Kisan Andolan, led by former Aam Aadmi Party leader Yogendra Yadav, was stopped on Sunday evening on the Gurgaon-Delhi border near Kapashera, a spokesperson of Swaraj Abhiyan said.
The march was launched from Thikriwal village in Punjab's Barnala district on August 1, with members of the Jai Kisan Andolan -- avowedly fighting for justice for the nation's farmers -- from Punjab, Haryana, Mahararstra and Uttar Pradesh participating in it.
On Sunday, the march began from Nuh, after a stopover at Rozka Meo Village, at 10 a.m. and moved towards Gurgaon.
The march passing through Sohna and Badshapur reached Kapashera but Delhi Police denied it entry into Delhi, saying tractors were not allowed on the roads of the national capital.
Yadav showed some papers to the police, claiming to have permission to enter the national capital, but in vain.
The march was heading towards Jantar Mantar, where a farmers' rally is scheduled on Monday.
On being denied entry in Delhi, Yadav tweeted: "& now starts the Tamasha by government! Police not letting our march move inside Delhi. Even though we have had the permission since July 8."
