The first cracks in opposition amity after the stinging defeat in the Bihar elections surfaced on Sunday, with a senior leader of the Tejashwi Yadav-led Rashtriya Janata Dal (RJD) calling out the Congress for putting up a half-hearted fight. "Congress became a shackle for Mahagathbandhan. They had fielded 70 candidates but didn't hold even 70 public rallies. This is not right," Shivanand Tiwari said.
