JD(U), a key constituent of NDA, on Friday voiced concern over the Opposition alliance "deviating" from its national agenda but said it has not given any ultimatum to BJP over walking out of the coalition.
"The alliance of NDA exists for now but the alliance has to continue under the norms of national agenda of NDA under which the coalition has functioned so far," JD(U) President and NDA Convenor Sharad Yadav told reporters here.
He said certain events had taken place which went against the tenets of NDA's national agenda.
The relations between JD(U) and BJP have been strained following the appointment of Gujarat Chief Minister Narendra Modi as the chairman of the BJP's campaign committee chief for next Lok Sabha polls.
Yadav said that JD(U) had maintained that Modi's elevation was an internal matter of BJP.
"But we have objections to the remarks made by BJP leaders after that. At Goa, speeches that happened went beyond the national agenda," he said.
Meanwhile, CPI(M) leader Sitaram Yechury also met Yadav to discuss the political situation in the country.
