Reacting to BJP MLA Dr Navjot Kaur Sidhu’s remarks against PPCC chief Capt Amarinder Singh, terming him “incapable of bringing about reforms in Punjab”, a group of about 15 Congress leaders, including several MLAs, today asked her to mind her own business rather than trying to meddle in the affairs of other parties.The leaders, including Rana Gurjeet Singh, Kewal Dhillon and Rana Gurmeet Singh Sodhi, said Dr Sidhu was feeling frustrated as her party had disowned her and the Aam Aadmi Party was not prepared to accept her.In a joint press statement, the party leaders said the Congress and Amarinder did not need any certificate from anyone.
