A small football ground ringed by nondescript apartments, a shadowy saloon, rundown cooperative stores, a 132-year-old redbrick school and the remains of an abandoned temple. That's Harinavi maidan in Sonarpur, a chaotic middle-class suburb 40 km out of Calcutta. But, as local tea-kiosk owner and part-time political commentator Kalipada Ghosh points out, the turf is also an important political meeting ground. It falls within Calcutta South, one of West Bengal's most keenly contested parliamentary constituencies, and is on the fringes of Jadavpur and Diamond Harbour, two other equally hot constituencies.
