The singer Anne-Marie has been crowned the winner of the 2021 Strictly Come Dancing Christmas Special.

The 30-year-old pop star and the professional dancer Graziano Di Prima were victorious after performing a thrilling cha cha, which earned them a perfect score of 40 from the judges.

They landed joint top of the leaderboard with former Bake Off presenter Mel Giedroyc and Neil Jones, whose couple’s choice to Vanilla Ice’s Ice Ice Baby was also a huge hit.

Anne-Marie, who is also a coach on The Voice, looked visibly shocked when her name was called out during the festive instalment of the BBC One show on Christmas Day.

She said: “I cannot believe it. I’m so proud and so happy for this opportunity to dance. It brought out a side of me I hadn’t seen in a long time. Thanks to Graz and the whole team. You have made my Christmas so special.”

The judges – Shirley Ballas, Craig Revel Horwood, Anton Du Beke and Motsi Mabuse -– were full of praise for Giedroyc’s comically infused routine, which also included dancing penguin holograms.

Ballas said: “You absolutely sum up the joy of Christmas. It was joyous, what a way to close our show, well done.”

The Repair Shop’s Jay Blades and Luba Mushtuk scored 34 for their jive to the Only Fools and Horses theme song, Hooky Street.

Blades was surprised with a message from Only Fools and Horses star David Jason before they received their judges’ scores for their routine, which featured a chandelier in the beginning, a nod to one of the sitcom’s most popular episodes.

Sir David, 81, known for playing Derek “Del Boy” Trotter in the BBC sitcom, joked in a video message that given they were dancing to the show’s theme song, “there will be a royalty” and ended his message with one of the show’s famous lines saying: “You know it makes sense.”

First Dates host Fred Sirieix and Dianne Buswell opened the show with a quickstep, which earned them three 10s and a total judges’ score of 38.

Revel Horwood told the TV star: “I did think you were trotting around like a turkey but maybe that was the whole point darling,” but then commended Sirieix for the “fantastic energy” he brought to the routine.

TV presenter Adrian Chiles and professional dancer Jowita Przystał were praised for their American smooth, which head judge Ballas said was “so warming”.

The studio audience voted for their favourite, and their votes were combined with the judges’ scores to decide the winner after all of the routines.
