New Delhi: Former finance minister Yashwant Sinha met BJP patriarch L.K. Advani on Wednesday, a day after the BJP's old guard including Advani took on Prime Minister Narendra Modi and BJP president Amit Shah, and demanded "thorough review" of the Bihar assembly poll debacle.

Meanwhile, union minister Nitin Gadkari defended Modi and Shah and demanded action against leaders who make unwarranted statements. However, there was no official word either from Advani or from Sinha, but sources said that the old guard of the BJP were not satisfied by a mere statement issued by the party on Tuesday night after their joint statement.
