A day after the Election Commission rejected his claims over the party's name and election symbol, Mr Yadav termed as "not in conformity with justice" its decision to recognise the group led by Bihar Chief Minister Nitish Kumar as the real Janata Dal (United) or the JD(U) and allow his faction to use 'arrow' symbol.
Mr Kumar and Mr Yadav parted ways after the former decided to join hands with the BJP in July, triggering a battle for the control of the party.
The EC, in its order issued yesterday, said the group led by Mr Kumar "has demonstrated overwhelming majority support" in the legislature wing as well as the majority in the national council of the party, which is the apex organisational body of the JD(U).
A senior party leader said that the order will be studied in detail by the lawyers and senior leaders, after which the Yadav-faction could consider to approach the high court against the commission's decision.
"We don't have dearth of symbols. We keep ourselves prepared for the fight. There have been talks with the Congress about seats (sharing) for the Gujarat elections. It will be announced by the Congress party," Mr Yadav told a press conference in New Delhi.
Asked about the new symbol his faction was going to adopt for fighting in the Gujarat Assembly elections, he said, it is the "autorickshaw".
He, however, did not announce the name of his new party.
Mr Yadav also raised doubts over the Moody's upgrading India's sovereign credit rating when the "Indian economy is in a bad shape and economists are endorsing the economic crisis in the country".
"The government patting its back on Moody's report is a joke on the people of this country. It is ridiculous that our own economists including Manmohan Singh are not being relied upon and the government is relying on the outside agency in measuring our economic situation," he said.
Mr Yadav also criticised the government for allegedly making it mandatory to link Aadhar card to avail ration by the poor under the National Food Security Act.
"Rations were earlier being supplied to the beneficiaries without Aadhar card, but now the government has linked it to Aadhar card and has put lakhs of people into miseries," he said.
