The Sun newspaper should be made to axe its pictures of topless models on Page 3 because it can lead to domestic violence, the minister responsible for women's rights worldwide tells The Independent on Sunday today.

Lynne Featherstone, the international development minister, said she would sign a petition to ban Page 3 because it had a "deleterious effect" on women.

Mrs Featherstone said she had experienced verbal abuse for her views on women's rights when she was equalities minister until this month. Mr Cameron has appointed her as "ministerial champion" to tackle violence against women across the world.

The petition, set up by Lucy Holmes and entitled "Take the bare boobs out of The Sun", had more than 30,000 signatures last night.

Admitting she would be called "mean" and "sour-faced" by some people, Mrs Featherstone said: "There is a real argument about what is OK in the public space. If you are on the Tube you may find Page 3 is facing you and your young daughter and you may not want that to be a role model for her.

"There is an army on the other side hurtling abuse. It's not simply about equal pay. It's about the constant drip, drip of women being sexualised in the public space [which] has a great bearing on attitudes and domestic violence.
