Former Chief Minister of Bihar, popularly known as Jan Nayak, Karpoori Thakur has been awarded Bharat Ratna posthumously. Thakur was in office twice, once for a brief period of six months between 1970 and 1971 and then between 1977-79.

The award will be conferred tomorrow - his birth anniversary. What does it mean for Bihar Politics? Let's decode.
