Members of the Lepcha tribe shout slogans during a public rally in Siliguri on November 16, 2011. Thousands of Lepchas from the Himalayan hills of Darjeeling, many clad in traditional attire, gathered in gratitude to West Bengal Chief Minister Mamata Banerjee for her support in the formation of the Lepcha Development Council. The Lepchas have called the inclusion of their native language Rongring in the education and governmental works and reservation for their tribe in government work opportunities.
