Infighting in the ruling JD-U in Bihar today took a new turn with state unit chief Rajiv Ranjan Singh Lallan today submitting his resignation to party president Sharad Yadav.<br/><br/>His resignation has, however, not been accepted by the party leadership which wants to resolve the differences between Lallan and Chief Minister Nitish Kumar at a time when state Assembly elections are due later this year. Lallan has been accusing Kumar, his one-time close associate, of behaving like a dictator and ignoring and overlooking genuine party workers and treating the party as his pocket organisation. <br/> <br/>When contacted, Mr Yadav said he has not accepted Lallan's resignation and has told him that his grievances would be addressed through discussions within the party in 10 days.
