India News: Sources said on Saturday that the government might ask Railway Minister Pawan Kumar Bansal to explain his role in the bribery case, in which his nephew Vijay Singla was arrested by the Central Bureau of Investigation (CBI) on Friday.

Bansal, however, has claimed that he had no knowledge about the matter. "I had no knowledge or clue about the matter at all. He or any other relative of mine does not and cannot meddle in my official functions and influence my decisions," he said.
