Owain Yeoman has joined a campaign to pressure Queen Elizabeth II's favorite store to stop selling foie gras.
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.
