The European Parliament adopted a resolution demanding more transparency on the transfer of financial data to the US authorities through the Society for Worldwide Interbank Financial Telecommunication (SWIFT). The resolution followed the release of an opinion by the European Data Protection Supervisor on the role of the European Central Bank in the case. The Parliament also called for its greater involvement in the negotiation of a final agreement between the EU and the US on the exchange of airline passenger data. The Article 29 Data Protection Working Party also released a new opinion on this issue.
