Marks and Spencer has changed the name of its popular Midget Gems sweets to avoid offending people with dwarfism.
The retailer has rebranded its version of the confectionery as Mini Gems following a campaign by disability academic Dr Erin Pritchard from Liverpool Hope University.
Dr Erin, who has achondroplasia, a condition which stunts growth, had previously approached supermarkets and sweet makers about changing the name of the product.
She raised her concerns that the use of the word "midget" is seen as derogatory for people with growth problems.
M&S is the first retailer to react to her campaign and has changed the labelling on its packaging.
An M&S spokeswoman said: "We are committed to being an inclusive retailer - from how we support our colleagues, through to the products we offer and the way we market them to our 32 million customers.
"Following suggestions from our colleagues and the insights shared by Dr Erin Pritchard, we introduced new Mini Gem packaging last year, which has since been rolled out to all of our stores."
In her recent book Disability Hate Speech, Dr Pritchard argues the word midget should be seen as a form of hate speech due to its origins in Victorian freak shows.
She wrote in Big Issue North: "Often referred to by people with dwarfism as the m-word, it is a term derived from the word midge, meaning gnat or sandfly.
"Its origin automatically dehumanises people like me. It was a term popularised during the Victorian freak show, where many disabled people, including people with dwarfism, were oppressed and exploited."
The supermarket chain Tesco has also said it will be reviewing the name of its product.
A spokesman said: "We are a diverse and inclusive retailer and we would not want any of our products to cause offence.
"We are grateful to Dr Pritchard for bringing this to our attention and we will be reviewing the name of this product."
