Some Congress party leaders are intrigued as to why Railway Minister Mamata Banerjee inducted former BJP strategist Sudheendra Kulkarni as a member of an expert panel set up by her ministry.

Although he was appointed to the panel earlier this month, the news broke only when Kulkarni quit the BJP and said he would remain a well-wisher of the party. This has left some Congress members wondering why the minister named a serving member of an opposition party to the panel.

“Does she know that he was also a one-time CPI-M card holder,” queried one, referring to the journalist-turned-speechwriter’s previous links with the Communist Party of India-Marxist, the main political adversary of Banerjee’s Trinamool Congress.
