Congress is set to launch a state-wide padayatra in Bihar from December 28 on the lines of 'Bharat Jodo Yatra', senior party leader Jairam Ramesh said on Sunday.

He said the 1,200-km-long march against the "communal agenda of the BJP" will start from Banka district and conclude in Bodh Gaya. It will cover 17 districts of the state.
