Siliguri, Jan 22 – West Bengal Chief Minister Mamata Banerjee on Sunday announced the formation of three more developmental boards for hill people and rolled out a Rs 100-crore project for tea garden workers. She claimed that the state government could have done much more developmental work for the hill people if it had complete control over local municipalities and the Gorkhaland Territorial Administration , a semi-autonomous body that administers the Darjeeling hills.
