This event for Comic Relief was hosted by the Overseas Development Institute (ww.odi.org) in Southwark, London.
The event centred on the theme of 'diaspora finance' from a research perspective.
The thing that surprised me the most was that it's the poorest that are hit by the biggest transfer fees to send money either home to, or across the borders within, Africa.
