The BJP is set to change leadership in Karnataka. Sources say Chief Minister Sadananda Gowda is expected to submit his resignation to party president Nitin Gadkari tomorrow; Minister for Rural Development, Jagadish Shettar, will be chosen as legislature party leader. Mr Shettar has the backing of BS Yeddyurappa, much as Mr Gowda had less than a year ago. A decision will be announced tomorrow after Mr Gowda meets Mr Gadkari in Delhi.
