Abba's 1992 greatest hits album Gold has become the third record to sell five million copies in the U.K.
The disc now joins the exclusive club alongside The Beatles' Sgt. Pepper's Lonely Hearts Club Band and Queen's Greatest Hits.
Britain's Official Charts Company boss Martin Talbot says, "This is another incredible record in a career of extraordinary achievements for Abba, who are unquestionably one of British music fans' all-time favourite acts.
"Over the past 20 years, one in every five households has bought a copy of Gold, which is a truly remarkable statistic."
