United States President Barack Obama walks along a path after posing for the leader’s group photo at the Summit in Huntsville, Ontario Canada. Walking along with our President is President of the Russian Federation Dmitry Medvedev and Canadian Prime Minister Stephen Harper. The G8 Summit has brought together leaders from the top economic countries in the world to discuss the global economy. Of course, the key issue on the agenda is how to improve growth. Other issues expected to be discussed include Global warming and petroleum use. Some say that the summit may see a confrontation between Obama and the new UK Prime Minister David Cameron over the BP oil Spill because BP is a vital company for the UK with one in six pensioners deriving income from their stock. It should be interesting.
