BJP's Devendra Fadnavis today said that he was confident of being the chief minister for the next five years amid growing tension with Shiv Sena over power-sharing in Maharashtra after the allies won a majority in last week's assembly elections. Mr Fadnavis also said that the BJP did not have any agreement with the Sena for a 50:50 arrangement for rotational chief ministership; the Sena insists it was agreed upon before the national elections. "There was no formula to split the chief minister's post... we have given no such formula," Mr Fadnavis said.
