Goa will have a new chief minister on Saturday as Manohar Parrikar resigns and heads to Delhi, where he is expected to take over as India's next Defence Minister after a union cabinet expansion on Sunday. Friday night, however, promises to be stormy in the tiny coastal state with what seems like a mini-rebellion in the ranks of the ruling BJP. Deputy Chief Minister Francis D'Souza has said he expects to be named chief minister tomorrow when the party's legislators elect a new leader.
