The Department for International Development (DFID) set out what the UK Government will do to reduce world poverty over the next five years in DFID's White Paper: Making governance work for the poor http://www.dfid.gov.uk/wp2006/ for both low income countries (LICs) and middle income countries (MICs).
DFID's commitment to MICs can be found in more detail in the middle income countries strategy 2005-2008
Under DFID's public service agreement (PSA) 2005-2008 the Department planned to allocate 90 per cent. of its bilateral programme to LICs to support them in reaching the millennium development goals (MDGs). DFID is meeting its objective.
