A QUOTE from an article saying Dominic Cummings' father-in-law named his horse Barack because it is "half black and half white" has gone viral.

Peter Jukes posted the quote from a story about Sir Humphry Tyrrell Wakefield, the father of Cummings' wife, Mary Wakefield, missing pheasant season to ride his horse the length of Britain.

The Fieldsports News article says: "Sir Humphry Tyrrell Wakefield who owns Chillingham Castle in Northumberland is riding his horse Barack, named because the horse is half black and half white."

It is presumed the horse is named after Barack Obama, who was criticised when he was elected president because his mother is white.

Twitter users hit out at the quote, with Scottish writer Mark Eglinton saying it is "absolutely appalling".

Jenny Stiles described the Cummings' situation as a "nightmare".

Another user linked to a video where Sir Humphry references eugenics, saying "success is in the genes".
