chief Lalu Prasad Thursday said that he was in no hurry to merge the various Janata parties, saying the proposed unity will take more time."I am not in a hurry for the merger of Janata 'parivar' because any work or decision finalized in a hurry can be bad," he told the media here.The former Bihar chief minister added that Samajwadi Party chief Mulayam Singh Yadav was the final authority on the issue."Mulayam Singh has been authorised by all of us to take the final decision."According to speculation here, Janata Dal-United leaders Nitish Kumar and Sharad Yadav are keen on an early merger of their party with the Rashtriya Janata Dal in view of the assembly elections this year.The Janata 'parivar' parties have spoken about uniting after suffering a rout in the Lok Sabha election last year.
