Keshubhai first became the state's CM in Mar 1995 but had to relinquish the post eight months later. In Mar 1998, he again took over the reins of the state and continued till Oct 2001.
When the party lost in two bypolls, Modi was chosen as Keshubhai's replacement. Ever since then, the latter has been unhappy. In the 2007 Assembly elections, he did not even campaign for the BJP. Neither did Keshubhai exercise his franchise that time.
Of late, there have been reports of the Congress which is the main opposition party in Gujarat instigating him to revolt. Since Keshubhai said a few days ago that his new party's ideology will be "Hindutva in its broad and liberal sense", it is not clear whether Congress leaders will ally with him against the CM.
