The chief executives body Acevo wrote to nine supermarkets and major retailers last year, including Asda, asking them to stop selling Health Lottery tickets immediately because they gave a lower proportion of proceeds to good causes than the National Lottery and other society lotteries.
A spokeswoman for Asda could not confirm whether any of its stores were still selling Health Lottery tickets. Nor would she comment on whether Acevo’s letter or adverse publicity surrounding the Health Lottery had contributed to its decision not to sell them more widely.
The supermarket said in a statement: "At Asda, we have a very simple philosophy: we're here to sell items people want to buy, and the Health Lottery has been treated like any other new product that's brought to us.
"We've trialled it in a minority of our stores and, based on that trial, we have no current plans to roll it out more widely."
Other retailers Third Sector spoke to, including WHSmith, Morrisons and Tesco, said they were still selling Health Lottery tickets.
