The leaders of the world's top industrialised nations are holding their latest G8 summit in Italy today. The meeting is taking place in the city of L'Aquila, which was devastated by an earthquake earlier this year. The state of the global economy is set to top the agenda, with the various heads of state set to discuss their ongoing efforts to stimulate economic activity. With unemployment still rising in developed countries, most observers believe the crisis has yet to reach its lowest point.
