WHAM's iconic holiday hit "Last Christmas" has once again claimed the top spot on the UK Christmas singles chart, marking their second consecutive year at number one. This marks a long-awaited achievement for the song, which originally peaked at number two upon its release in 1984. With the recent passing of WHAM member George Michael, this victory holds special significance for the duo. In addition to their success, Ladbaby, the YouTube channel known for its charity Christmas singles, has not released a festive hit this year. Meanwhile, over in the US, Mariah Carey's "All I Want for Christmas" reigns supreme, placing fourth on the UK chart. Will you be able to name all the Christmas number ones of the past 20 years?
