A week before the new version of the Band Aid single Do they know it's Christmas? is released, anti-poverty group the World Development Movement has condemned the song's lyrics as "patronising, false and out of date".
The new single reprises the words of the 1984 hit and includes the lines: "there's a world outside your window and it's a world of dread and fear, where the only water flowing is the bitter sting of tears".
WDM director Mark Curtis said: "The song perpetuates the myth that Africa's problems can be blamed on lack of rainfall and failed harvests. It conjures an image of a continent inhabited entirely by starving children with flies on their faces."
The new version, known as Band Aid 20, could raise £8m for famine relief in Darfur in Sudan, according to Sir Bob Geldof.
