Rs 26,728 crore. That’s roughly half the nation’s annual defence budget. And that’s the amount that, according to corruption tracker Transparency International, is paid in bribes across 10 service sectors in India each year. The NGO’s newest survey, conducted by its Indian office and ORG-Marg Research across 16 states and 5,127 urban and rural households, piles on some more bad news: the health sector is where palms are greased the most while, surprise surprise, the railways is the ‘‘least’’ corrupt. The NGO had earlier ranked India as among the 30 most corrupt nations in the world. This survey lists the decimal points of that statistic, looking at the spread of corruption in ten sectors: health, education, police, health, land administration, judiciary, power, taxation, railways, telecom and ration (public distribution system).
