Karnal, July 19 -- In a fresh controversy within the BJP, supporters of chief minister Nayab Singh Saini and cabinet minister Anil Vij had a brief face-off at Ambala Cantonment railway station when both groups resorted to sloganeering on Friday. Both groups gathered at the station to welcome Sant Ravidas Express, launched by Prime Minister Narendra Modi from Jalandhar Cantt to Varanasi via Ambala. Vij was the chief guest for the event organised by the ministry of railways in the presence of Rajya Sabha MP Kartikeya Sharma, BJP district president Mandeep Rana and mayor Akshita Saini among others. In a nearly two-minute viral video, Vij's supporters are seen raising slogans - "Bhai Anil Vij zindabad", "Haryana ka babbar sher zindabad" - after the train was flagged off. The minister seems to have objected once. The video shows another group raising slogans - "Nayab Saini Zindabad" and "Haryana ka Mukhyamantri Zindabad". They were joined by Rana and others. Later, as the Rana group reached near them, both hooted and cheered loudly, alerting the cops for a possible face-off. While Vij was not available for a comment, people close to him, who were present at the station, termed this an insult to the senior-most MLA of the party....
