Yesterday morning, the hashtag #BoycottSainsburys began trending on Twitter, after a group of right-wing shoppers became infuriated with claims that Lord Sainsbury had somehow been involved in the removal of the statue of slave trader Robert Milligan - which was pulled down on Tuesday night.
Some people believe that Lord Sainsbury's charity, The Linbury Trust – which has helped to fund the Museum of London Docklands – played a part in the removal of the statue.
However, it has not been confirmed whether or not Lord Sainsbury was involved in the decision.
In a statement about the statue's removal, the Musem of London Docklands says: "The Museum of London recognises that the monument is part of the ongoing problematic regime of white-washing history, which disregards the pain of those who are still wrestling with the remnants of the crimes Milligan committed against humanity."
Several right-wing Twitter users, infuriated by the rumours that Lord Sainsbury isn't a fan of slave traders, decided to start tweeting out #BoycottSainsburys, in a bid to get people to stop shopping at the supermarket.
However, it didn't go quite to plan, and the whole charade was quickly hijacked by other Twitter users, who got #BuySainsburys trending instead.
Some of the tweets were absolute gold.
"Lord Sainsbury says statues of slave owners should be taken down. Racist people reply with #BoycottSainsbury. I reply with #BuySainsburys, " wrote another Twitter user.
"Can we get a full list of everywhere racists are boycotting please? Imagine a world where you no longer have to encounter a single one of them. #BoycottSainsburys," said somebody else.
"Racists are calling for people to #BoycottSainsburys Go ahead, I'll start shopping there then #BuySainsburys," said someone else.
Manchester Evening News approached Sainsbury's, but the supermarket declined to comment.
