Romilly Greenhill, UK Director of the ONE Campaign, said:  “International aid already serves our national interest by helping to create a healthier, safer and more prosperous world.

“UK aid is already some of the most transparent in the world, in part because successive governments have learnt from the ‘arms for aid’ Pergau Dam scandal that they need to be up front with taxpayers about what is motivating aid programmes.

“Investing in fighting global poverty is not just the right thing to do but the wise thing to do.”
