Narendra Modi introduced a new political alphabet today with a dig at the Congress for a series of corruption scandals that have dogged it. "A for Adarsh, B for Bofors, C for CWG and D for Damad Ka Karobaar (son-in-law's business)," said the BJP's star campaigner in Jaipur, the capital of election-bound Rajasthan. The last refers to allegations of malpractices in business against Robert Vadra, the son-in-law of Congress president Sonia Gandhi.
