Update: we've updated the tinned tuna league table for 2011. Who's at the top? Who's languishing at the bottom? Find out...
NB Three other major supermarket chains were excluded from the final table for the following reasons:
Waitrose: does not stock its own-label
tinned tuna. Waitrose stocks John West products, but does not stock Princes.
Iceland: Iceland does not have an own-label tinned tuna range.
Somerfield: has been purchased by the Co-op and once the acquisition and integration has been completed, Co-op policies will apply.
This league table has been compiled on the basis of data obtained from four sources:
- Retailer and brand supplier responses to a product survey issued by Greenpeace commencing in May of this year.
- Correspondence with retailers and brand suppliers arising from the survey.
- Information obtained from Greenpeace Active Supporters engaging in spot checks of their local supermarkets; and
- Material that is publicly available on retailer and brand supplier websites.
