RJD president Laloo Prasad Yadav on Wednesday asked prospective partners to adopt a realistic approach on seat-sharing to inflict ‘‘resounding defeat’’ on the NDA. ‘‘Instead of making untenable claims, secular parties should take into account the winnability of candidates,’’ Yadav said on his arrival from Delhi. ‘‘I spoke to Paswan and I am confident that a mutually acceptable seat-sharing formula will emerge,’’ he said, adding talks were still on with the Congress. —(PTI)
