Mamata leaves secretariat after 36 hours, explores legal options

Addressing the media before leaving the seat of power "Nabanna" in neighbouring Howrah district, Banerjee threatened to explore "legal options" if the army was not withdrawn.

"We have never seen such arrogance (by Centre). If Army is not withdrawn we will explore legal options," she said.

Banerjee said she had great respect for the army, but was "sad" at the manner in which they were being used for "political vendetta".
