Britain’s biggest supermarket Tesco is facing backlash from certain customers vowing to boycott the supermarket chain over its new “inclusive” Christmas advert.

The advert, which features families from all walks of life, shows clips of a Muslim family celebrating the holiday, exchanging presents and cooking Christmas dinner.

The new advert is part of a series of five short videos set to be released in the run up to Christmas to promote diversity. Tesco ends the advert with the phrase “Everyone welcome”.

But some customers are far from happy about the inclusion of a Muslim family in an advert that celebrates a Christian holiday, also commenting on the supermarket selling halal meat in Tesco stores.

One customer tweeted: ”I object strongly to your anti- Christian Xmas advert how dare you politicise our festival in order to appease lefty political correctness. You have lost me as a customer now, you should rethink your advertising campaign, British people still live here.”

“Hey, Tesco. .. I don’t mind ONE BIT about your Xmas ads featuring Muslims wearing headscarves. .... I’m looking forward to your Eid ads. .. Featuring Christians – wearing crucifixes,” wrote another Twitter user.

“Tesco is trying to appeal to Muslims to buy their food at Tesco . So that raises a point. Muslims use my local Tesco but nothing is marked up as HALAL . So it follows all meat sold in Tesco must be HALA. WHY IS TESCO ALLOWED TO SELL HALAL MEAT TO CHRISTIANS,” wrote one irate user.

“Everyone is welcome at Tesco this Christmas and we’re proud to celebrate the many ways our customers come together over the festive season,” said the supermarket in an official statement.

“We want our customers to know that however they choose to do Christmas, and no matter what they need, we can help – Everyone’s Welcome at Tesco.”

The supermarket also said that it “will celebrate the many ways we come together at Christmas, and how food sits at the heart of it all”.

Many shoppers welcomed Tesco’s advert and see the marketing campaign as a representation of a modern, inclusive Britain.

“If you’re offended by the Tesco Christmas advert then PLEASE boycott the stores so I don’t have to see your racist faces when I’m choosing my Brussels sprouts,” wrote one supportive Tweeter.

“Imagine being so empty and full of hate that a Muslim family in a Christmas advert offends you,” said another Tweet in support of Tesco’s message of diversity.
