Now it has emerged that the pottery behind the viral image - which plays on the fact the mug can't hold liquid as it has holes in the side - hail from Yorkshire.
Lee Cartledge, of Bentham Pottery in Ingleton created the mug featuring the word "Brexit" in lettering which sabotages its ability to carry liquid.

"It looks brilliant but when you actually use it it's not so good."
Mr Cartledge posted a picture of the mug to Facebook with the words: "Limited edition commemorative Brexit mug available from 29th March 2019."
Despite him expecting only a few comments from friends, the post has since been shared tens of thousands of times by people across the world.

Mr Cartledge had not initially intended to sell the mug commercially, but is now considering making an initial batch of 60 mugs for sale at "a good price" as "it's sort of a work of art in a way".
