The chief minister of the southern Indian state of Karnataka BS Yeddyurappa has resigned days after an anti-graft panel indicted him in an illegal mining scandal. BS Yeddyurappa quit on Sunday following a decision by the leaders of his Bharatiya Janata Party (BJP), the BBC reported Monday. The anti-corruption report alleges the scam cost the exchequer more than $3bn about (?1.8bn) from 2006-2010. Yeddyurappa denies any wrongdoing. Correspondents say illegal mining has been rife for years in Karnataka. The state produces about 45 million tonnes of iron ore a year and exports more than half of it to China.
