A day after the grand alliance won the popular mandate, he also said he would soon launch a nation-wide agitation against the "kattarpanthi" or hardline communal, forces.
"There is anger against Prime Minister Narendra Modi across the country. The Bihar results have given some relief to the countrymen... Nitish Kumar will look after Bihar and I'll move around in the country to launch a movement against communal forces," Mr Yadav said.
The RJD chief, whose party returned to the political forefront in the state after 10 years, said PM Modi's Lok Sabha constituency Varanasi would be the first stop for him where he would search with the help of his 'lantern' (RJD's symbol) the development promised by the prime minister during Lok Sabha polls.
"I'll find out if Varanasi has become Kyoto as promised by Modi, the MP from Varanasi," he said in a dig at PM Modi.
Targeting the BJP-led government at the Centre, Mr Yadav claimed, "Nobody is feeling safe in the country... they have terrorised everybody... 'bolte thay acche din ayenge, par itna burra din kabhi nahi dekha desh (they used to say good days will come, but the country has never seen such bad days)."
Mr Yadav, whose two sons Tej Pratap Yadav and Tejaswi Yadav won the Mahua and Raghopur seats, respectively, as RJD emerged as the single-largest party in Bihar Assembly, also said in an apparent reference to BJP chief Amit Shah that "they used to talk about 'jungle raj' and 'chara chor' (fodder thief)... people are the best judge who is what."
He also criticised the media and political commentators for reiterating words like "jungle raj" and "chara chor" and said it was in bad taste. They hoped they would not repeat such phrases in the future.
