Richard Corbett: Small nation that needs our help in refugees crisis

I have just had the harrowing experience of visiting the world's largest refugee camp. Over half a million people '“ the equivalent of a city the size of Leeds or Sheffield '“ are crammed into hastily erected bamboo and canvas shelters and tents on a few hillsides and valleys that, in about 50 days, will be hit by the monsoon torrential rains which will wash away the shelters of a quarter of them and turn the whole area into a muddy morass.
