The G-20 Leaders' Summit on Financial Markets and the World Economy was held in London on 2 April 2009 at the ExCeL Centre. It followed the first G-20 Leaders Summit on Financial Markets and the World Economy, which was held in Washington, D.C. on 14–15 November 2008. Heads of government or heads of state from the Group of Twenty Finance Ministers and Central Bank Governors (G-20), plus some regional and international organisations attended. Due to the extended membership it has been referred to as the London Summit.
The Group of Twenty Finance Ministers and Central Bank Governors (known as the G-20 and also the G20 or Group of Twenty) is a group of finance ministers and central bank governors from 20 economies: 19 countries, plus the European Union (EU). It has also met three times at heads-of-government level: Washington, D.C. in November 2008, London in April 2009 and Pittsburgh in September 2009. The next 2010 G-20 Summits are being held in Toronto on June 26-27 and Seoul on November 11-13.
