Union Minister Ramdas Athawale, who on Friday warned the Shiv Sena that an alliance with the Congress and the NCP to form the government in Maharashtra could not last, declared this morning that the BJP had taught the Sena, its former ally in the state, a lesson. Mr Athawale's comment came mere hours after a massive overnight twist in Maharashtra that saw the BJP's Devendra Fadnavis take oath as Chief Minister and the Ajit Pawar, the nephew of NCP chief Sharad Pawar, become Deputy Chief Minister.
