The practice of keeping animals such as lions, elephants and tigers in circuses is currently prohibited in many European countries including The Netherlands, Greece and Austria, but U.K. officials have yet to implement a boycott, despite an attempt being made by Members of Parliament to pass legislation last year (15).

Pamela, who is currently visiting London, posted the letter to the Prime Minister on Wednesday (12Oct16), calling on her to bring forward a ban.

"Madam Prime Minister," the letter reads. "One of the things that I love the most about the U.K. is its strong reputation as a nation that opposes cruelty to animals. That's why my mouth dropped when I learned that Britain still has not banned wild animals from circuses."

The Baywatch star, 49, who is an active member of animal protection organisation People for the Ethical Treatment of Animals (PETA), adds: "Animal acts are embarrassingly archaic and have no place in modern Britain-or anywhere else. I urge you to join the growing list of nations around the world that have put an end to this form of abuse. I'm currently in the U.K. and would welcome the chance to meet with you about this issue."

If May agrees to a meeting with the actress, she won't be the first politician Pamela has tackled on animal welfare issues this year - in January (16) she spoke to French parliamentarians, calling on them to ban foie gras, the controversial goose liver pate dish which is one of France's national delicacies.
