The most distinctive and controversial is “Parasites” – two large, ugly sculptures of shoppers carrying McDonald’s, Tesco and Primark bags.

They lurk by the bandstand and are attracting numerous photographers.

Artist Rene Farda, 29, said it was inspired by the worst side of “crazed” shopping culture you see in town on a weekend.

He said: “They don’t think what’s behind the products they buy.

“They contribute to problems all round the world.”

The black paint reflects a saying in his native Slovakia – if you do evil, you are said to carry a black stain.
