It seems it's not just the NSA. GCHQ, the British equivalent of the NSA, was spying on attendees at the 2009 G20 summit in London, including the country's allies.
Of course, it might be expected that there would be espionage at such events, but GCHQ used various ways to manage to collect as much data as possible from everyone involved.
For example, he used Internet cafes that he filled with keyloggers and email interception software.
The organization also used a special tool to break into the BlackBerries favored by many politicians and diplomats.
The Turkish finance minister and his party were particularly targeted by GCHQ spies.
A few weeks ago, NSA whistleblower Edward Snowden left the agency with thousands of classified documents.
The Guardian has today uncovered another document (a PowerPoint slide) which outlines GCHQ's surveillance methods.
The revelation may cause some problems for the British diplomatic corps, and we mention it perhaps because everyone knows about the spy game that is played at such gatherings, without anyone admitting it.
However, the timing of this particular leak coincides with the G8 summit which is once again taking place in the United Kingdom.
