The plenary would be preceded by a meeting of partys national executive on December 26-27 which would be chaired by outgoing party chief LK Advani, BJP vice-president Mukhtar Abbas Naqvi said in a statement here. The executive would take stock of current political and economic issues, besides discussing organisational matters, he said.
The Mumbai convention, to mark the silver jubilee of the partys establishment, would discuss future strategies to corner and expose failures of the Congress-led coalition in tackling corruption, unemployment, price rise, poverty, illiteracy and illegal migration, he said.
Meanwhile, the partys top central leaders are meeting here on Wednesday to decide on whether to call a meeting of its legislators in Madhya Pradesh to elect a new chief minister.
Amid hectic lobbying by ministers and legislators of both sides here, the partys general secretaries and other senior leaders are expected to take a decision on the assurance given to Uma Bharti that the Madhya Pradesh issue would be looked into after the Bihar elections.
Though Mr Advani is said to be personally in favour of restoring the chief ministership to Ms Bharti, almost all the second generation leaders are reported to be vehemently opposed to her return, sources said.
The RSS too is said to have strong reservations about her return, particularly after she targeted joint general secretary Suresh Soni and charged him with interfering in state party affairs.
