Adele tops 2015 album chart with 25
Adele's 25 was the biggest album of 2015 - despite only being released in November and not being available to stream.
The singer's comeback third album smashed charts records, selling 2.486 million copies by the end of the year, the Official Charts Company said.
The album reached the top spot even though 25 is not available on streaming services.
This means her figure is made up entirely of digital purchases and sales of the physical CD.
Streams through services such as Spotify and Apple Music have been counted in the Official Albums Chart since March, with 100 streams equating to one purchase.
The album sold 800,307 copies in its opening week. By day 29, Adele had become the fastest artist ever to smash through the two million sales mark.
The singer did fail to reach the top of the list of the biggest songs of 2015, taking sixth place with Hello. However, the hit comeback single has been named as the fastest seller of the year.
In second and third place in the list of the biggest albums of 2015 were Ed Sheeran's x and Sam Smith's In The Lonely Hour - despite both albums being released in 2014.
Sheeran released x in June 2014 but it shot to the top of the charts again in July 2015 ahead of his sold-out Wembley Stadium shows. It finished the year on 971,000 combined sales - with a grand total of 2.66 million to date across its lifetime.
The 24-year-old's debut album, +, also made the Top 40 four years on from its release - placing at 38.
Smith's In The Lonely Hour notched up 893,000 combined sales in 2015, bringing it to 2.14 million in total. It hit number one on four occasions and also achieved a record-breaking 67 weeks in the Top 10.
Elvis Presley came in fourth place, achieving posthumous success with his 2015 album If I Can Dream, an orchestral reworking of his biggest hits.
Cilla Black's Very Best Of, which became her first number one album ever following her death in August, was 25th on the list.
Justin Bieber's Purpose made fifth place, with combined sales of 645,000, despite never reaching number one in the charts - while One Direction's Made In The A.M. only made it to 14th place.
