He said the threat of disease and exploitation by extremist groups meant the disaster would have a “long tail”.
After visiting different flood relief camps of Sukkur on Wednesday,
he said that in one of the worst hit regions, the “aftershocks” (of the flood disaster) would “last for a long time.”
He said the worldwide response was too slow but praised Britain’s donations.
He said that the British government has committed euro 33 million in aid to help deal with the disaster. Meanwhile, the charity appeal for Pakistan has raised a total of euro 42 million.
“I think of the sheer scale of this, it is really quite difficult to comprehend,” said Deputy Prime Minister of UK, and added that we have to make a huge effort to provide important emergency aid, but really stick with this for a long term.
He stressed the flood waters had not drained out in many areas and there was a “real danger of diseases taking hold.”
He also warned the disaster could increase the influence of extremist groups, the danger always is that you get groups who have an ulterior motive who provide aid to try to curry favour,” he added.
He said that the worst floods to hit the country in decades have left at least 1,600 people dead and an estimated 20 million homeless.
