David Cameron has called for EU leaders to double their funding in the fight against Ebola.
The Prime Minister demanded an £800 million pledge after writing to 26 fellow leaders and the European Council.
It comes after one of the doctors who discovered the virus, Professor Peter Piot, said the rest of Europe was not doing enough to tackle the epidemic.
Downing Street said at the moment the total contribution from the EU was just £400 million.
Mr Cameron vowed to use next week's meeting of European leaders to press for more action.
