Microsoft billionaire Bill Gates is to highlight how progress in agriculture and health is tackling extreme poverty across the world.
The computer pioneer-turned-philanthropist will present his vision for improving lives at the launch of an anti-poverty initiative at the London School of Economics.
Gates will cover the key themes of his annual letter from the Bill and Melinda Gates Foundation.
He is set to meet individuals who will be trained to engage with a diverse range of communities in an attempt to tackle poverty.
Elisha London, UK director of the Global Poverty Project, said: "We are thrilled that Bill Gates has chosen the launch of the Global Poverty Ambassadors to deliver his annual letter.
"His vision and commitment is an inspiration for these ambassadors who will mobilise their own communities in the fight to end extreme poverty."
Peter Marks, group chief executive of the Co-operative Group, which has sponsored the event, said: "The Co-operative's six million customer members can be vital in the fight against global poverty.
"From becoming a Global Poverty Ambassador, to committing to buy Fairtrade products, to resolving to switch to a Co-operative Bank account, there is something we can all do to help."
