Obviously,Arvind Sharma is paid the price to shun his dissidence &come back to the fold of the party at this time when each single vote matters a lot to the Congress.This is very much revelant from his statements that Congress is his party,Sonia his leader and he was never against the party etc...height of shamelessness Then,why at all he rebelled?His taking the name of Sonia is only to keep the top boss in good humour & preempt any disciplinary action if to be thought by his party after the trust motion.
