Anandpur Sahib MP and Shiromani Akali Dal candidate for the Lok Sabha seat, Prem Singh Chandumajra today attacked Congress’ nominee Manish Tewari, calling him a rolling stone. “Fearing defeat, Tewari had left Ludhiana in 2014 and this time he tried to contest from Chandigarh… He is an outsider and doesn’t even have basic knowledge of the constituency,” Chandumajra said.
