Seizing on the remarks made by outgoing Punjab CM Capt Amarinder Singh against PPCC chief Navjot Singh Sidhu over his alleged links with the establishment in Pakistan, the BJP has asked the Congress high command whether they would take cognisance of the allegations and take action. BJP leader Prakash Javadekar said, “Capt has called Sindhu anti-national. This is a very serious allegation. BJP is asking only one question to Congress that why Sonia Gandhi, Rahul and Priyanka are silent? We demand Congress to speak on this issue and put their version. Will Congress take cognizance of these allegations and take action on it,” Javadekar added. Former Union minister Javadekar’s statement comes a day after Amarinder Singh stepped down as the Punjab CM saying he felt “humiliated”. On Saturday, Singh, who has long been embroiled in a bitter battle with Sidhu, called him “anti-national”, “incompetent” and a “security threat” to the state and the country.
