LONDON’S Green Party Euro-MP Jean Lambert has demanded an immediate investigation into claims that the US has routinely spied on top EU officials.

German news magazine ‘Der Spiegel’ reported claims made by US whistle-blower Edward Snowden that the US National Security Agency (NSA) has been routinely spying on EU officials and institutions.

Ms Lambert will use a parliamentary debate to call for an immediate EU investigation – before the summer – and to put current talks on a controversial EU-US trade deal on hold until it is concluded.

She said: “It is alleged that there had been a serious breach of international law, and a shocking breach of trust between allies, and the EU must investigate this immediately – and not postpone any decision until after the European Parliament breaks for the summer.

“Obviously there can be no progress on a trade deal between the EU and the US while these allegations remain unanswered.

“The last few days have shown how urgently we need an international agreement on data protection.”
