Bimal Gurung reappeared as mysteriously, and dramatically, as he had vanished from public view three years ago. Even more dramatic was his announcement last week on severing ties with the BJP, a party his faction of the Gorkha Janmukti Morcha (GJM) helped establish base in the Darjeeling hills. But that is only half of the unfolding story—Gurung’s perceived surrender to West Bengal chief minister Mamata Banerjee has, by all likelihood, deepened the political complexities in Darjeeling, where the demand for a separate state of Gorkhaland, comprising parts of northern Bengal’s plains, has been the dominant theme for decades, especially since the mid-1980s.
