British TV presenter Chris Packham stars in the latest campaign for animal advocacy organisation Project Slingshot, calling on Marks & Spencer to stop selling factory-farmed salmon.

Packham commented 'Salmon are extraordinary animals which have evolved to travel thousands of miles. Confining them in sea cages exposes them to excessive levels of parasites, a range of diseases and practices that cause extreme suffering... M&S should use its influence to help end factory-farmed salmon'.
