The European Parliament's decision to keep documents on MEPs' expenses a secret contradicted past declarations, Green MEP Sven Giegold stated. Giegold authored a resolution adopted last year, which said parliament should publish documents related to internal decision making. Parliamentarians are entitled for a monthly lump sum of €4,416 to cover office-related costs, but are not required to keep receipts or to return unused funds. In July, 14 EP vice-presidents held a meeting to determine how the system ought to be reformed and opted for minimal changes and the least transparency.
