Lose the Lads' Mags campaign group has called for the Co-operative to stop stocking the magazines altogether, after it issued a deadline for publishers to 'cover' them up.
Sophie Bennett, a spokeswoman for the campaign said:
Thousands of people have called on retailers to stop selling lads' mags like Nuts and Zoo.
The Co-operative's actions show our voices are being heard. Yet the Co-operative are attempting to sell their customers short.
The so-called 'modesty bags' they are demanding from publishers are designed to allow the Co-operative to continue profiting from sexist, harmful lads' mags - but just a bit more discreetly. That's not what corporate social responsibility looks like.
