BJP on Sunday termed as "sad and unfortunate" JD(U) leaving the NDA fold and charged its former ally with walking out despite repeated assurances on the prime ministerial candidate issue.
"The break-up of NDA is sad and unfortunate," Leader of the Opposition in Lok Sabha Sushma Swaraj said on micro-blogging site Twitter.
BJP Vice President Mukhtar Abbas Naqvi termed it as "very unfortunate" but said, "This is not the end of the world. More allies will come to NDA."
Recalling a famous Hindi song, Naqvi said, "A friend has done a deed which even an enemy would not do."

However, the BJP leader said that the elevation of Gujarat Chief Minister Narendra Modi as head of Election Campaign Committee -- the reason for JD(U) to walk out of NDA -- was an irreversible decision and there would not have been any backtracking on the issue.
"After Gujarat Chief Minister's appointment as head of the Election Campaign Committee, our party president Rajnath Singh had clarified to JD(U) several times that it will not be changed," Naqvi said.
The BJP leader maintained that JD(U) should understand that Modi is the rising star. "The writing is on the wall. People will not forgive those who do not see it," Naqvi said.
