"I have worked in Bihar and Delhi for almost equal tenures. You talk about corruption. Corruption in Bihar is one fourth of what it is in Delhi," said Singh, who is slated to be named adviser to Chief Minister Nitish Kumar on infrastructure.

Anybody who does good work for the people would get their support irrespective of caste and religion, he said.
JD(U) MP Sabir Ali and party spokesperson Sanjay Jha, too, were present on the occasion.
