Morrisons has come under fire from Friends of the Earth for selling products containing palm oil.
The environmental pressure group is concerned that palm oil plantations are destroying the rainforest habitats of the orang-utan. FoE ran an advert in the Independent this week slamming Morrisons for refusing to join the Roundtable on Sustainable Palm Oil.
A Morrisons spokesman said: "We take the concern about palm oil cultivation very seriously and are supportive of the aims of the RSPO to promote sustainable palm oil production. We will continue to monitor the situation closely."
