Charities face a fresh Olympic funding threat with the launch of a game to raise money to help British athletes prepare for Athens.
The British Olympic Association is in negotiation with a number of commercial organisations to run an Olympic-themed game, probably a scratchcard, in the run-up to the games this summer.
Philip Pope, the association's media manager, said: "It is our responsibility to drive as much revenue into Olympic sport as possible and we are looking at a number of opportunities."
Luke FitzHerbert, co-founder of the Directory of Social Change, said the game would cannibalise lottery money to good causes.
"Now the voluntary sector has made itself dependent on the proceeds of gambling, it is in competition with anyone else who promotes gambling," he said.
