The real success over the past year in the campaign against corruption was won by Subramanian Swamy, a lone ranger, by chipping and chiselling away within the existing legal system, and working the levers of the law and politics. It was Swamy’s interjection, right from the time he sought prosecution of Telecom Minister A Raja in the 2G scam case — and his doggedness — that turned the heat on India’s biggest corruption case, and has ensured that Raja is cooling his heels in the slammer for a year, come February.
