Congress has said the government has left crucial issues in One Rank One Pension Scheme in the dark. Briefing media in New Delhi today, party spokesperson Abhishek Manu Singhvi said, different statements have come from government's side on VRS so far and there is a need for clarity on the premature retirement issue. <br/><br/>Questioning the five year revision provision of the pension, Mr Singhvi said, the UPA had accepted automatic increase in pension when salary increases, but five year revision supported by present government is an injustice.
