In the new ad, which will be broadcast during ITV’s This Morning today, Fairy works her magic and Duckie learns to fly out of his reach as they soar over a Christmas table spread of M&S food.

The new campaign is the first in a series of eight showing the adventures of the two Christmas characters, concluding with a New Year’s Eve special.

M&S Food director of marketing and hospitality Sharry Cramond said: “This Christmas we know families want a cosy but special get together at home.

“Our ad brings to life what we have to offer – the perfect menu to deliver that warm, fuzzy, festive feeling.

French said: “I had the time of my life lending my voice to the Fairy that brought Percy Pig to life last year.

“I was so excited that M&S wanted to bring her back for more adventures and discover more of that amazing food… and, this time with a trusty new sidekick!”

Saunders added: “When the call came in asking me to be in the M&S Christmas ad, I didn’t have to think about it.

“And to bring the team back together for it? It was a Christmas must.

Cramond said: “We know value is front of mind for families and our food range is about offering the best possible quality at the best possible price – from essentials to showstoppers – alongside that all-important dose of M&S Christmas magic.”

“We couldn’t resist reuniting two British icons in Dawn French and Jennifer Saunders with the British icon that is M&S.

“It’s a match made in heaven as they lend their voices to the glamorous Fairy and adorable Duckie and it’s fantastic to have them on board.

“I predict Wylie the dog will go on to be a huge star!”
