Chief Minister Mamata Banerjee on Thursday said she has written to the Centre to allow poppy cultivation in West Bengal so that people of the state can enjoy the delicacies prepared with it. Speaking in the assembly, Banerjee said 'posto' or poppy seeds are costly as it is cultivated only in a few states "Bengalis love posto. Why should it be cultivated in only four states? Why will it not be cultivated in West Bengal, despite it being on our menu every day?" she asked. "Why will we have to purchase posto from other states at high prices? Why will West Bengal not get permission of cultivating posto here? I will ask members of the opposition to write to the Centre on it," she added.
