"Who says so? There is no truth in it," Yadav told reporters last evening when asked to comment on reports of his changing his parliamentary constituency.
"I will keep fighting elections from Madhepura constituency," the four-time MP from the Yadav-dominated seat, said before leaving for his constituency.
The report, he alleged, is a "part of a sinister campaign by BJP".
Some news reports had said Yadav might choose a "safe" seat like Nalanda, which is considered a pocket borough of Chief Minister Nitish Kumar, for the coming general election instead of Madhepura.
The JD(U) chief said he had been raising problems of backward Kosi region and would continue to do so in future too.
Yadav said he would take initiative after January 31 to bring Left and other regional parties on one platform against Congress and BJP. But, he did not identify the regional parties he would contact for the purpose.
