Vivienne Westwood wants to design an ethical alternative:
Peta campaigners had spoken to people watching the guards at Buckingham Palace about the use of the skins of Canadian black bears to make their hats.
"Most people think it's fake fur and when they find out it's real and it takes one bear to make a hat, they are appalled."
A spokeswoman for the MoD said: "The MoD is not opposed to the use of synthetic materials as an alternative to bearskins, provided such materials meet the requirement for a high quality product that performs adequately in all weather conditions. Regrettably, a suitable alternative continues to prove elusive."
