Britain’s falling popularity in many Islamic and developing countries is damaging British charities’ ability to help with disaster relief and reconstruction in war zones, according to Oxfam.

The UK-based international development charity says it was forced to turn down British government funding for disaster relief in Lebanon after last year’s Israeli-Lebanon conflict. It says its reputation would have been damaged by association with UK foreign policy, given the government’s failure to call for a ceasefire during the conflict.
