THIS could prove to be the Bharatiya Janata Party's biggest crisis ever. The Gujarat tangle has shown that public display of personal ambition and defiance are no longer taboo in a party that has traditionally prided, and sold, itself on its discipline. 7'he rebellion by 47 party MLA's and the consequent sacrifice of Keshubhai Patel as chief minister after a face-saving 'victory' in the vote of confidence in the State Assembly on October 7 and rehabilitation of the rebels are bound to have an impact on the party's national campaign to capture the next Lok Sabha.
