1215 Tribune News Service Chandigarh, May 12 In yet another attempt to quell dissent within the Punjab Congress, four more Cabinet Ministers, namely Gurpreet Kangar, Balbir Singh Sidhu, Bharat Bhushan Ashu and Vijay Inder Singla, have demanded suspension, if not expulsion, of Navjot Singh Sidhu as his acts amounted to “open rebellion” against the party. Minister Kangar, who was present in a meeting held a few days ago at the residence of minister Sukhjinder Randhawa, distanced himself from the meeting. He said he had gone there for some work. Only two days ago, three other ministers — Brahm Mohindra, Sunder Sham Arora and Sadhu Singh Dharamsot — had urged the party high command to take strict disciplinary action against Sidhu for anti-party activities.
