"The days of UPA government are numbered and it will fall after the assembly elections in five states," party leader M Venkaiah Naidu claimed while addressing party workers here at a function to mark the assuming of office by newly appointed Karnataka unit president D V Sadananda Gouda.
The party appointed its Mangalore Lok Sabha member Gouda to head the state unit replacing Jagadish Shettar, who has joined the BJP-Janata Dal (Secular) coalition ministry in the state.
Naidu exhorted party men to maintain discipline and follow the party's constitution strictly.
He termed Congress president Sonia Gandhi's resignation from her Lok Sabha seat and National Advisory Council as a "big drama" saying, "She quit fearing disqualification."
BJP National General Secretary T Ghelot, incharge of party affairs in Karnataka, hailed the budget presented by the BJP-JDS government in the state.
Deputy Chief Minister B S Yediyurappa, who presented the budget, said he would soon lead a delegation to Gujarat to study power sector reforms in that state which has ensured 18-hour power supply in rural areas.
The new state unit president Gouda assured that he would work towards strengthening the party at grassroots level, taking workers into confidence.
