The decision is the result of a year-long campaign by a pressure group, the Topless Front, which says women should be treated the same as bare-chested men.

Campaign leader Astrid Vang, 20, who took her shirt off with others to protest at a leisure centre at Christmas, said: “We women would like to decide by ourselves when our breasts should be sexual and when not.

“In swimming pools they should not and that is why the breasts should not be covered - We will bathe topless just like men.”

The Danish campaign was inspired by a Swedish group called Just Breasts, which was formed after two women were asked to cover up their breasts by a lifeguard at a public pool near Stockholm.

Swedish protesters carried out several full-frontal marches in their country but are still campaigning for bare-chested equality.

One of their leaders, 22-year-old Ragnhild Karlsson, said: “We want our breasts to be as normal and desexualised as men’s, so that we too can pull off our shirts at football matches.”

Activists expect a flurry of similar campaigns-across Europe, including in Britain.

Authorities in Vancouver, Canada - often considered to be a bastion of Victorian values - have allowed topless women in swimming pools and on beaches for several years.

The only protest against the move came from lifeguards who said they had problems knowing what to hold when rescuing swimmers in difficulties.

In Copenhagen yesterday, the city’s Culture and Leisure Committee voted overwhelmingly to allow topless bathing.

Frank Hedegaard, of the Socialist People’s Party, said: “I cannot understand what some people find so offensive about women’s breasts.

“This decision is important in order to stop the idea that women’s bodies are only sex objects.”
