The UK will take a leading role in the fight against a new type of antibiotic-resistant superbug, David Cameron has said.
Mr Cameron says his scientific experts have said superbugs are among "the most serious health problems the world faces".
"When we've had these problems in the past, whether it is how we tackle HIV and Aids, how it is possible to lead the world and get rid of diseases like polio, Britain has taken a lead and I think it is right we take a lead again," he told The Times (£).
The paper also reports that the Prime Minister raised the issue in private talks with Barack Obama and German chancellor Angela Merkel at the G7 last month.
An international group of experts has been established to help stimulate the development of a "new generation of antibiotics".
The panel will be led by Jim O'Neill, the former chief economist at investment bank Goldman Sachs, who has been tasked with working out how governments could pay pharmaceutical companies to produce rarely used drugs.
