Fifty-one point five billion dollars: that’s the staggering amount that UN relief chief Martin Griffiths has asked donors for, to help 230 million extremely vulnerable people in nearly 70 countries next year.

Although relief needs are growing, Mr. Griffiths is under no illusion that less than half of what he’s requested will be provided.

Which is why he’s convinced that the money should come from other sources, including non-earmarked development funding, and even a windfall tax on energy companies, as he explains to UN News’s Daniel Johnson.
