Officials at People for the Ethical Treatment of Animals (PETA) are spearheading calls for bosses at London's Fortnum & Mason to introduce a ban on the controversial pate.
Welsh star Yeoman, who plays Special Agent Wayne Rigsby in the hit U.S. drama series, led a protest outside the store on Wednesday (15Jun11), standing front of a mocked-up "crime scene" and holding a placard that read: "F&M: Investigate Compassion - Ban Foie Gras".
The actor says, "In the U.K., foie gras production is literally a criminal procedure - so why is a shop that prides itself on its British heritage still selling this cruel product? We're encouraging all compassionate people to shop elsewhere until Fortnum & Mason stops selling foie gras."
Other stars who have already signed up to the campaign include James Bond legend Sir Roger Moore and British actor Steven Berkoff.
