Chandigarh, April 26 The Shiromani Akali Dal (SAD) today demanded immediate resignation of Chief Minister Capt Amarinder Singh as well as his Cabinet colleagues for ordering a “political inquiry” into an unfortunate incident by a handpicked officer whose findings have been termed malicious, irrational and absurd by the High Court. Addressing a press conference here, SAD leader Bikram Singh Majithia said besides the CM, others who had held meetings to frame the chargesheet in the case included Navjot Singh Sidhu, Sukhjinder Singh Randhawa, Tript Rajinder Singh Bajwa and Kushaldeep Dhillon. He said the CM and ministers should put in their papers immediately, but action should be taken against all leaders who politicised the case.
