NEW DELHI: BJP on Saturday hit out at Congress after its Punjab president Navjot Singh Sidhu reportedly called Pakistan PM Imran Khan his "elder brother" during a trip to Kartarpur Sahib, alleging the opposition party sees terror groups like IS and Boko Haram in Hindutva and finds a "bhai jaan" in Khan. A purported video of Sidhu being welcomed by a Pakistani official on behalf of Khan has gone viral in which he is heard saying Khan was like a "bada bhai" to him and that he loved him a lot. As BJP seized on the issue to target Congress, party spokesperson Sambit Patra said it is a serious matter of concern for India. He claimed that there was a larger design at work, and Sidhu's comments were linked to a number of Congress leaders, including Rahul Gandhi, criticising Hindutva. BJP IT department head Amit Malviya tweeted, "Rahul's favourite Navjot Singh Sidhu calls Imran his 'bada 'bhai'. Last time he had hugged Gen Bajwa, Pakistan Army's chief, heaped praises. Is it any surprise that the Gandhi siblings chose a Pakistan loving Sidhu over veteran Amarinder Singh!"
