Leaders of the Group of Eight rich nations are set to backtrack on their landmark pledge at the Gleneagles summit in 2005 to increase development aid to Africa to $25bn a year.

A draft communiqué obtained by the Financial Times, due to be issued at the group's July summit in Hokkaido, Japan, shows leaders will commit to fulfilling "our commitments on [development aid] made at Gleneagles" - but fails to cite the target of $25bn annually by 2010.
