"Our national leaders L K Advani, Rajnath Singh, Arun Jaitley and Sushma Swaraj will be descending in the city for poll campaign by attending Sankalpa Convention on April 8," state party spokesman C T Ravi told reporters here.
BJP's Central Election Committee will announce the list of its candidates in the first week of April, he said.
The party is consulting important office-bearers of all the districts to recommend only one name from each constituency to avoid confusion, he said.
Replying to a question, Ravi denied any confusion in BJP in finalising the names of candidates, saying internal democracy exists in the party.
Ravi also said the party would take appropriate action against Karnataka Janata Paksha President B S Yeddyurappa's son and Lok Sabha member B Y Raghavendra for anti-party activity.
