West Bengal CM Mamata Banerjee has reportedly handed over the command of TMC's Lok Sabha unit to her nephew and the party's National General Secretary Abhishek Banerjee, replacing Sudip Bandyopadhyay. The change in leadership has come as Mamata expressed disappointment over poor coordination among TMC's Lok Sabha team, hinting at the public fallout between MPs Kalyan Banerjee and Mahua Moitra.
