Campaigning anti-poverty rockers Bono and Bob Geldof teamed up this week (begs04Jun07) to put pressure on U.S. President GEORGE W. Bush ahead of the G-8 summit in Germany. The pair, accompanied by Senegalese singer Youssou N'Dour, discussed efforts to alleviate poverty in the developing world ahead of the meeting of world leaders in Rostock, which kicked off on Wednesday (06Jun07). Bush has praised Bono in the past for his humanitarian work, hailing him "an amazing guy". However, he was forced to miss out on talks with his political colleagues about development spending today (08Jun07) after he was taken ill with a stomach complaint. Leaders agreed a $60 billion (GBP30 billion) pledge to fight diseases such as AIDS in Africa and restated promises to double development spending on the continent.
