A difference between Tory and Labour
Labour has been making much of their support for a new law which would enshrine in legislation the commitment to spend 0.7% of national income on foreign aid. Labour themselves first made that commitment when they were running the country a decade ago. Yet it was the present coalition government which actually hit that target last year for the first time ever, as you can read at https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/300084/Prov-ODA-GNI-2013a.pdf There is a graph on the site which shows that Labour in government never got the share of aid above 0.5%. And that was at a time when they had inherited a very strong economy from Ken Clarke and it was far easier to find money for things. Writing targets into law is not actually the best way of hitting them: it's just the best way to score a political point.
