Queen are officially the first act to sell six million copies of an album in the UK.
Three decades after their 'Greatest Hits' album was released in 1981, it continues to rack up strong sales.
The Official Charts Company, announcing the milestone, said it has been estimated that one in four British homes has a copy of the album, which includes hits such as 'Bohemian Rhapsody' and 'Another One Bites The Dust'.
Guitarist Brian May said the figure was "incredible". In a video message for OfficialCharts.com, he said: "I just want to say thanks to everyone who has supported us through the years, we hope to continue to serve you."
