Genoa 2001. Evian 2003. Edinburgh 2005. Violence has once again hit the G8 summit.Anarchist protests have broken out in Scotland’s capital ahead of the gathering of the world’s richest nations. Several people were detained during clashes with police, and around 20 were injured. On the political front, the US president has signalled that Britain should not expect favours in return for backing the Iraq war. George W Bush told a British television channel he did not see the relationship with Tony Blair as a ‘quid pro quo.’ G8 officials have drafted a text on climate change but it is said to be a tame document as America’s allies are anxious to secure US support. Britain has made poverty relief a central plank of its year-long presidency of the G8. London’s bid to double aid to Africa received a boost when Germany backed that goal. The G8 meeting, due to begin tomorrow, has attracted a rare degree of international attention. On Saturday ‘Live 8’ concerts were held around the world to raise awareness of developing world issues. They were attended by more than a million people.
