The 2009 G20 London Summit was the second meeting of the G20's heads of government and heads of state, held in London at the ExCeL Exhibition Centre to discuss international trade, management of globalization, trade liberalization, financial markets, and world economy. Prime ministers from the G20 attended the event, along with finance ministers, central bankers, and secretary-generals from various regional and international organizations also represented. Due to the extended membership, it has been referred to as the London Summit.

In June 2013, British newspaper The Guardian revealed that the British government's intelligence and security agency, the Government Communications Headquarters (GCHQ), had spied on computer and phone communications of foreign politicians attending the summit by intercepting their phonecalls, emails, and monitoring computers, in some cases even ongoing after the event via keyloggers that had been installed during the summit. Their actions were sanctioned by the British government and intelligence was passed to its ministers. The policing tactics at the event raised some controversy, particularly over the death of Ian Tomlinson.
