The Bharatiya Janata Party's 'Parivartan Rath Yatra' will roll on Sunday from the temple town of Charbhuja in Rajsamand district in Rajasthan.
Deputy Prime Minister Lal Kishenchand Advani will flag off the yatra and it would be led by the state unit chief of the BJP, Vasundhara Raje.
Advani will address a public meeting before flagging off the yatra, which will wind its way through all 200
assembly constitutencies in the next three months before concluding in Jaipur in July, a party spokesman said.
Prime Minister Atal Bihari Vajpayee is likely to address the concluding ceremony.
Leader of opposition in the state assembly, Gulab Chand Kataria, said the yatra was aimed at "freeing the people [of Rajasthan] from the bad governance of the Congress ministry."
