"Bengal will never be allowed to be divided and the state government is determined to tackle the situation strongly," Mukherjee told reporters here.
Describing the renewed movement by the GJM demanding Gorkhaland statehood as an "irresponsible decision", Mukherjee said the movement had no support of the people in the state including many of those in the hills.
Accusing the Centre of instigating into the issue, the minister said Chief Minister Mamata Banerjee would act in time according to the law to control the situation and restore law and order in the hills.
The minister expressed hope that good sense would prevail and the GJM would finally withdraw their movement.
