This is a big story in Indian news today. The current prime minister, Narendra Modi was elected partly because he promised to bring black money that was stashed abroad, back to the country. A Herculean task and one that he hasn't done much about so far.
It interests me how this information can be used against the relevant people. Will it be a mere name-and-shame or can they use a leaked source in a court of law? I don't think so.
People in many countries avoid taxes and in India this is especially egregious since close to 97% of the population does not pay any income taxes[1]. For a population of 1.25 billion with 400m below the poverty line, this is not good.
