Marks & Spencer has been embroiled in a new sexism row after being accused of 'normalising porn' with its new porn star martini drink in a can.

The cocktail is a blend of passion fruit and vodka and costs £2 for a 250ml tin. Marks & Spencer claim to be the first supermarket to sell it pre-mixed in a tin.

Angered parents on Mumsnet wrote that they did not want to have to explain what a porn star is to their children while food shopping at M&S, and feminist campaign group Object! said the supermarket was "normalising porn."

The group tweeted: "Marks & Spencer normalising porn. And if you try to complain online, the system rejects the word 'porn'. Mixed messages huh?

One Mumsnet user wrote: "It may be an actual cocktail, but I don’t madly want to explain to my small daughter what a porn star is, while shopping for cake."
