Eurojust supports wire-tapping of Skype conversations

Mr Thuy stressed that the wiretapping would not affect "normal users", but would have to be carried out only as part of a criminal investigation.

Eurojust's talks with prosecutors and police officials from member states, as well as legal experts would be led by Italian prosecutor Carmen Manfreda.

"There are 30 different legal systems all across the EU, so we expect the talks to take several months before first results are presented," Mr Thuy added.

Skype, an Danish-Swedish business developed by Estonian programmers that was sold to E-Bay in 2005 and has over 350 million customers worldwide, is said to be un-spyable by intelligence services.

In its press release, Eurojust says that "Skype has so far refused to share its encryption system with national authorities."

However, Skype claims that it has "extensively debriefed Eurojust on our law enforcement programme and capabilities."

"Skype cooperates with law enforcement where legally and technically possible. Skype remains interested in working with Eurojust despite the fact that they chose not to contact us before issuing this inaccurate report," Brian O'Shaughnessy, head of corporate communications at Skype said in a statement.

The Italian anti-mafia prosecutors requested Eurojust to coordinate this initiative, pointing that criminals in Italy were increasingly making phone calls over the internet in order to avoid getting caught through mobile wiretapping.

Bavarian authorities allegedly also attempted to wiretap Skype conversations and commissioned an IT firm to do this, but were not successful, according to documents obtained by Piraten Party, a movement promoting Internet freedom.

According to Eurojust, customs and tax police in Milan have overheard a suspected cocaine trafficker telling an accomplice to switch to Skype in order to get details of a 2kg drug consignment.
