Rashtriya Janata Dal (RJD) supremo Lalu Prasad is likely to reach Patna on Friday after a long stay in Delhi following his kidney transplant surgery in Singapore in December last year. With the news of Prasad's arrival, RJD workers in the state capital, who have been waiting for him for a long time, are jubilant and are now preparing for his grand welcome. "Father is coming to Patna, we have lots of work to do", Tej Pratap Yadav, Bihar Environment, Forest & Climate Change minister and the elder son of RJD supremo, tweeted on Thursday.
