The plan was to flag off the yatra from Sitab Diara but the venue was moved to Chhapra in view of the bad road condition and waterlogging.

Advani, accompanied by Leaders of Opposition in the Lok Sabha and Rajya Sabha, Sushma Swaraj and Arun Jaitley respectively, arrived by a chartered plane. He is scheduled to address a public meeting at Chapra and proceed by road to Patna where he would be addressing another rally in the evening.

During his yatra, Advani would stay in Bihar for two days and would be addressing meetings at Ara and Buxar on Wednesday before leaving for Varanasi in Uttar Pradesh.

Advani has said the initiative is aimed at raising awareness about corruption. He added his 'rath yatra' would put pressure on the government to retrieve black money stashed away in foreign shores and pursue good governance as well as clean politics for a change.

 Nitish Kumar has lauded Advani for his endeavour which, he believes, would raise public consciousness about large-scale corruption in the country and bring back black money locked up in foreign banks.

Advani plans to cover around 300 km a day in his special rath or modified bus during his 12,000-km campaign called Jan Chetna Yatra. The yatra will mobilise public opinion on electoral and judicial reforms, black money and scams faced by the UPA government. It will begin from the birth place of Jayaprakash Narayan at Sitab Diara village on the Bihar-Uttar Pradesh border.

On Monday, Advani avoided ruling out his candidature for the Prime Minister’s post in the run-up to the next Lok Sabha elections due in 2014. 'Who will be the Prime Ministerial candidate; the party will decide when the polls come. It is still more than two years away. However, the government is functioning in a manner that it seems it can fall any time,' he said at a press conference.
