Why is the UK such a generous global aid donor and should it be? The coalition government legislated to ensure Britain spent 0.7% of its national income on international development and it is now one of the very few countries to meet this United Nations target for such spending. With financial pressures on public services at home remaining acute, Jo Coburn asks why most politicians still support the idea, despite public criticism and press campaigns about wasted money. In her quest, she investigates the history of the UK's support for overseas aid and examines what makes so many politicians willing to risk voters' displeasure on the issue.
