Yesterday, high street giant M&S stunned shoppers in the UK, as it launched legal action against Aldi over its Colin the Caterpillar cake 'lookalike'.

Shoppers quickly reacted to all of the drama, and it's safe to say that peoples' opinions are well and truly split.

The retailer said the similarity of Aldi's product leads customers to believe it is of the same standard and "ride on the coat-tails" of M&S's reputation with the product.

M&S wants Aldi to remove the product from sale and agree not to sell anything similar in the future.

It posted a picture of Colin on its Instagram with caption: "You might have seen @official_colinthecaterpillar is in the news... Colin won't be commenting, but says thanks for your support. #OGColin"

Aldi responded to the post, tweeting: "This is not just any court case, this is... #FreeCuthbert."

However, M&S shoppers were divided, with some who agree that M&S is in the right and others who wondered why Aldi was being singled out when other supermarkets also make a version of the Colin the Caterpillar cake.

Hanna replied: "Aldi are really hungry caterpillars but nothing beats the OG Colin from M&S."

While Caz wrote: "Don't let Aldi get away with it they're always ripping off M&S products and packaging."

Kirsty simply wrote: "Team Colin," and Celina commented: "Love Colin!" while another said: "Colin forever."

Adele said: "Colin is the best," with Shelly replying: "It's not just any caterpillar......." and Victoria wrote: "You can't replicate the OG caterpillar."

Kiri commented: "Trademarks are registered for a reason, good luck Colin!"

And Jules wrote: "Definitely the original and the BEST no competition."

However, lots of people thought that M&S had taken it too far, according to the ECHO.

Claire said: "I think most supermarkets do a caterpillar cake!! It's just ALDI's tastes better lol, all a bit petty really!"

Staci was extremely vocal and wrote: "It's not the best when the sponge is dry and it's covered in hard chocolate. Every supermarket has its own versions. Learn to play the competitive game rather than take people to court.

"Some people have to make what best they can for their kids and families. If M&S charge £5 for the cake and others £3 if funds are tight where are they going to shop? Long gone is the be kind message Christ it's more caterpillar eats caterpillar."

Em agreed: "All the supermarkets have their version of a caterpillar cake... Why is Aldi being singled out? Genuine question."

To which one person replied: "I wondered this too so I've spent my afternoon Googling. If you Google pictures of them, the Aldi one really is a close match to the M&S one looks wise so I think that's why. Yes the other supermarket ones are still caterpillars but they look different/distinct!"
