Independant – Gordon Brown will hail a new £1.5 billion drive to eradicate deaths from malaria in the developing world by 2015 at an emergency United Nations summit on world poverty and disease.
The initiative, to develop a vaccine and distribute bed nets and sprays over the coming years, is expected to save the lives of one million people who die from malaria every year.
It will be announced by the Prime Minister and Microsoft boss Bill Gates in New York, where 90 world leaders are gathering at the UN to discuss getting progress on the Millennium Development Goals back on track.
Mr Brown is also meeting Wall Street hedge fund chiefs to discuss the global financial turmoil which has sent shockwaves through the markets over the last week.
