"The alliance is for the sake of people to safeguard them from divisive forces represented by BJP and RSS," he said.
It is a 'long fight' against elements out to 'destroy' the secular fabrics of the country, the JD(U) president said.
He, however, evaded a direct reply as to who will be the leader of the alliance if the tie-up between JD(U), RJD and Congress continued in the assembly election in the state next year.
"Do not worry it will be decided when the time comes," he told reporters at Patna Airport.
"I myself am the leader of the leaders," was his enigmatic reply when pressed on whether Lalu Prasad or Nitish Kumar would be the leader of the alliance.
On RSS chief Mohan Bhagwat's remarks that India is a Hindu nation and Hindutva is its identity, Yadav said it was against such thoughts and beliefs that JD(U) had separated from BJP.
Yadav will campaign for the alliance candidates in the August 21 bypoll to 10 seats, which is being considered as the precursor to the Bihar Assembly election next year.
He would be addressing a rally at Hajipur, Lok Sabha constituency of LJP chief and Union minister Ramvilas Paswan.
