Amazon, Google and Wish have removed neo-Nazi and white-supremacist products being sold on their platforms following an investigation by BBC Click.

White-supremacist flags, neo-Nazi books and Ku Klux Klan merchandise were all available for sale.

Algorithms on Amazon and Wish also recommended other white-supremacist items.

All three companies told the BBC that racist products were prohibited on their platforms.

Oren Segal from the Anti-Defamation League (ADL), an anti-hate organisation, said the companies needed to “constantly be on top of what the algorithm is recommending”.

He said algorithms had to be “taught to be responsible”.

One of the items found for sale on Amazon was a white-supremacist flag featuring a Celtic Cross.

The ADL said the image featured on the flag was “one of the most common white-supremacist symbols”

One shopper had left a “review” of the product in June, stating: “This is a neo-Nazi flag. Amazon should not be profiting from this.”

However, another reviewer said the flag would be “good for use in parades” and thanked Amazon for “making it happen”.

Amazon’s algorithms recommended another controversial flag that shoppers had “frequently bought together”.

Both symbols were worn by the Christchurch gunman when he killed 51 people in 2019.
