British aid to double as 19m people face acute hunger, but summit unlikely to end conflict amid Saudi-UAE tensions

The British foreign secretary, Yvette Cooper, will urge Sudan’s warring parties to “cease bloodshed” during a major conference on Wednesday, which analysts believe is unlikely to deliver a significant step towards peace.

The talks in Berlin – held on the third anniversary of the start of Sudan’s ruinous war – are expected to help address a catastrophic funding shortfall that is compounding the world’s worst humanitarian crisis.
