When will the 2020 Christmas Number 1 be announced?

Here's all the important details about this year's Official Christmas Number 1.

It's beginning to look a lot like Christmas - and for the act who manages to climb to the top of the Official Christmas Chart, it really will be the most wonderful time of (an otherwise difficult) year.

Celebrating a UK Christmas Number 1 is a British festive tradition that goes back decades, starting in 1952, when Al Martino claimed the snow-capped summit with Here in my Heart. 

Since then, a wide variety of tracks have scored that special Number 1 – from festive faves and wintry ballads, to the occasional dance banger and, of course, a sprinkling of quirkier tracks that could, in all honesty, only reach Number 1 at Christmas.

Friday December 25 - yep Christmas Day itself - is the date to get in your calendar: that's when the full Christmas Top 40 is counted down on BBC Radio 1's Official Chart.

Tune in to The Official Chart with Katie Thistleton on BBC Radio 1 on December 25 from 2-4pm to hear the Christmas Top 40 countdown and the exclusive reveal of the winner of the Official Christmas Number 1 2020.

You can also catch Top Of The Pops on Christmas Day, more details of the broadcast to come. The full Top 100 Official Christmas Singles Chart and Albums Chart will be published on OfficialCharts.com from 5.45pm.

Last year the Official Christmas Number 1 went to YouTube sensation and dad blogger LadBaby who, along with his wife Roxanne and two young sons, scored his second Christmas chart-topper in a row with I Love Sausage Rolls, a festive-come-meaty spin on rock classic I Love Rock N' Roll. Proceeds from the single went to food-bank charity The Trussell Trust.

No word on whether LadBaby is going for a third Christmas Number 1 yet, though his new festive advert with Walkers suggests something could be in the works.
