TMC demoted from being national party to regional party: Adhir

Congress leader Adhir Ranjan Chowdhury on Tuesday said Mamata Banerjee-led TMC used to be national party, but then it became a regional party and its stature decreased. "Be it Goa, Tripura or any other state - they tried every place but failed," he added. "If Mamata thinks she can become PM of the country...it can be imagination only," he added.
