Anti-corruption used to be something of a policy backwater for development agencies. When I started working at DFID’s London office in 2003 I sat next to the anti-corruption team. They were an enthusiastic lot, but there were only 3½ of them, and they were working against the spirit of the times in many ways, with increasing amounts of UK aid going directly to developing country governments in the form of budget support. Nowadays, anti-corruption is flavour of the month in UK development circles. The Prime Minister is putting a lot of emphasis on it, and will hold an anti-corruption summit in May this year. There is a cross-Government anti-corruption action plan. There have been two reports on the issue from the UK aid watchdog – the Independent Commission on Aid Impact – and Parliament’s International Development Committee is now getting in on the action. The issue also seems to be getting more attention globally, with the new UN Sustainable Development Goals putting much more emphasis on corruption than the previous Millennium Development Goals. In the midst of all this, I played my own personal role in the anti-corruption ‘surge’, becoming the first (I think) dedicated anti-corruption adviser for a DFID country office, in Tanzania from 2012-2015.
