"The Lok Samvad programme, which was scheduled for tomorrow, stands cancelled due to an indisposition of Chief Minister Nitish Kumar," said an official release.
It added that the JD(U) chief was down with fever.
Lok Samvad is a public interface programme of Kumar held every Monday. It aims to collect the feedback of the people on the implementation of the development schemes and gather new ideas to strengthen 'sushasan' (good governance).
Kumar or the JD(U) has not commented so far on Friday's CBI raids in four cities in connection with a corruption case, in which RJD chief Lalu Prasad, his wife Rabri Devi and son Tejashwi are among the accused.
