BREAKING: British Intelligence Spied on G20 Members

Documents uncovered by the NSA whistleblower, Edward Snowden, reveal surveillance of G20 delegates' emails and BlackBerrys, reports The Guardian.

Foreign politicians and officials who took part in two G20 summit meetings in London in 2009 had their computers monitored and their phone calls intercepted on the instructions of their British government hosts, according to documents seen by the Guardian. Some delegates were tricked into using internet cafes which had been set up by British intelligence agencies to read their email traffic.

The revelation comes as Britain prepares to host another summit on Monday – for the G8 nations, all of whom attended the 2009 meetings which were the object of the systematic spying.

The Guardian says during G20 meetings in April and September 2009 GCHQ [the UK's UK Government Communications Headquarters]  used what one document calls "ground-breaking intelligence capabilities" to intercept the communications of visiting delegations.

This included:

• Setting up internet cafes where they used an email interception programme and key-logging software to spy on delegates' use of computers;

• Penetrating the security on delegates' BlackBerrys to monitor their email messages and phone calls;

• Supplying 45 analysts with a live round-the-clock summary of who was phoning who at the summit;

• Targeting the Turkish finance minister and possibly 15 others in his party;

• Receiving reports from an NSA attempt to eavesdrop on the Russian leader, Dmitry Medvedev, as his phone calls passed through satellite links to Moscow.

The documents suggest that the operation was sanctioned in principle at a senior level in the government of the then prime minister, Gordon Brown.

"For the first time, analysts had a live picture of who was talking to who that updated constantly and automatically," according to an internal review.
