Gavin & Stacey should make one of its beloved characters vegan for the show finale according to PETA.

The animal rights organisation has appealed to writers and producers James Corden and Ruth Jones, suggesting character Pam should reject her "Three Steaks Pam" moniker and prepare a vegan Christmas dinner instead for the final scene.

This plea follows the announcement that the show's much-anticipated last episode is to be aired on Christmas Day.

During the early episodes of the show, Pam pretended to be vegetarian.

PETA vice president of programmes Elisa Allen penned the letter advocating for a change in Pam's eating habits.

She argues: "By making Pam vegan for the finale, you’ll ensure that – whether or not she gets ‘drunk, drunk’ this Christmas – she’ll enjoy a ‘well lush’ spread while sparing clever pigs, curious turkeys, and industrious fish suffering."

PETA believes making Pam vegan could encourage audiences to consider animal-free alternatives for their Christmas meals.

PETA has highlighted the impact traditional Christmas dinner can have, pointing out that around nine million turkeys are slaughtered annually for festive meals in the UK.

They suggest that any person who chooses a vegan diet, following Pam's example, would save almost 200 animals each year.

The organisation - with the motto "animals are not ours to eat" - offers advice and resources for people considering going vegan.

Their campaign for dietary change extends beyond concern for animal welfare.

They argue that a shift towards widespread vegan consumption could reduce global greenhouse gas emissions by 70 per cent by 2050.
