Hundreds of world leaders and politicians will descend on Istanbul on Monday in a nominal attempt to reform the global humanitarian system, despite criticism that their summit is a photo-opportunity that will achieve little.

Angela Merkel is the highest-profile western leader due to attend, while Britain will be represented by development secretary Justine Greening. About 6,000 senior aid workers will also participate in debates and panels at the two-day event.
