“Through the story of Skye and Nathan, we celebrate friendship and are reminded of the joy of experiencing Christmas for the first time.”

As soon as Britons watched the advert this morning, many took to social media to express their opinions on the jumper, as well as the film itself.

Twitter user Emma Lewis wrote: “Oh John Lewis. The kiss, the ending, the jumper. I just can’t cope! Talented actors and a lovely story. Also the tune.”

Nicola Kemp commented: “Love this, love the soundtrack, love the emotion, love the festive jumper. Is it too early for mince pies.”
