BBC Radio 1 is to reveal which singles and albums have sold the most in the UK in the last ten years.
Between Christmas and New Year, Radio 1's Nihal will count down the top 100 best-selling singles and albums of the decade – as compiled by the Official Charts Company.
On 28 December between 1.00 and 4.00pm Nihal will unveil the best-selling albums of the last ten years.
Then at the same time through 29 to 31 December, Nihal will run down the most popular 100 singles of the decade, culminating on New Year's Eve with the best-selling song of the decade.
Nihal says: "Oh my gosh! Ten years of music and I get to host the countdowns of the decade – time to start digging in the crates."
