Bill Gates co-founder of Microsoft: "Thank you Bob for inviting me to be here (Live 8) today. You Richard Curtis and all the organisers deserve a lot of credit for pulling off this amazing event. I believe that if you show people the problems and you show them the solutions they will be moved to act.

"The huge turnout for Live 8 here and around the world proves that thanks to the leadership from people like Tony Blair and Gordon Brown the world is beginning to demand more action on global health and poverty."
