Even as Railway Minister PK Bansal has offered to resign after the CBI arrested his nephew Vijay Singala in the cash for jobs scam, the Congress core committee is set to meet today to decide on his fate. However, sources say that the Congress is all set to back Bansal based on the aspect that there is nothing to establish his direct involvement in the case and that the CBI is yet to name him. But the opposition wants Bansal out.
