Bahujan Samaj Party (BSP) president and Uttar Pradesh Chief Minister Mayawati kicked off her party's election campaign in Bihar on Sunday.
"Please bring BSP to power at the Centre to serve all, particularly the poor and weaker sections of the society," Mayawati said in her address at a public meeting in Bhagalpur town, about 200 km from Patna.
"I appeal to you to support and vote only for BSP. Don't vote for any other party because they have betrayed you and did not fulfill their promises," Mayawati said.
The BSP leader accused the Congress, the Bharatiya Janata Party (BJP) and other political parties of ignoring the plight of the poor in the last six decades.
"The socio-economic condition of the majority of the poorest of the poor has not changed till date," she said.
Mayawati said that poor people from Bihar were forced to migrate to big cities in search of livelihood as successive governments in the state and Centre did not bother to develop Bihar.
BSP is contesting alone in Bihar on all 40 seats in the state.
Bihar will go to the polls in four phases -- April 16, 23, 30 and May 7 -- to elect 40 members to the Lok Sabha.
