The European Union's executive body has decided to ax its investigation into the allegations that the U.S. spied on EU citizens, angering lawmakers in the bloc's Parliament who called for tougher actions against America's surveillance regime.
The European Commission's decision is a major blow for the European Parliament who have staged a series of inquiries into the snooping claims and called for the suspension of a controversial financial data-sharing agreement between the EU and the U.S. aimed at tracking terrorists' funds.
Members of European Parliament (MEPs) are outraged by the Commission's decision.
"Investigation? What investigation? It consisted of asking them asking the U.S., 'Hey did you take our data illegally?' That is not an investigation," Dutch MEP Sophia in 't Veld told CNBC in a phone interview from Brussels.

"Our citizens are being spied upon. Our communications are not safe. There is mass surveillance of EU citizens on EU territory. It is unacceptable that the Commission refuses to make full use of its powers and protect our rights. We will use any instrument we can to make our citizens get the protection they are entitled to."
But the European Commissioner for home affairs Cecilia Malmström said she was satisfied that the U.S. did not breach the rules of the data sharing agreement and decided to drop any investigation into surveillance activities.
