Aldi is donating profits from its Cuthbert Caterpillar cake to charity, despite the supermarket being taken to court by M&S for infringing trademark laws.
Sales of a limited edition version will benefit Teenage Cancer Trust and Macmillan Cancer Support.
Shoppers have praised Aldi for its latest proposal to Marks & Spencer in the Colin v Cuthbert the Caterpillar cake saga.
Aldi posted a message on its Facebook page asking M&S if they would consider teaming up and 'take a stand' against cancer.
The supermarket suggested that the two retailers could come together and raise money for the respective cancer charities, which both stores support.
The message read: "Hey Marks and Spencer, we’re taking a stand against caterpillar cruelty. Can Colin and Cuthbert be besties?
"We're bringing back a limited edition Cuthbert next month and want to donate all profits to cancer charities including your partners Macmillan Cancer Support and ours Teenage Cancer Trust. Let's raise money for charity, not lawyers #caterpillarsforcancer."
Aldi quickly followed the open letter to M&S with a plea to the other big supermarkets to come together too.
