The XL album, which is number one for a 20th week in the US this week following Adele's six Grammy wins, sold more copies abroad last year than any other British album has in a calendar year this century.
It is joined in the chart at number three by Adele's first album 19 with 2.3 million overeseas sales, while Parlophone act Coldplay's Mylo Xyloto is runner-up with 3.2 million copies bought abroad. It debuted at number one in more than 30 countries following its release last October.
Despite having been released back in 2009, Mumford & Sons' Sigh No More sold enough copies overseas last year to make it to fourth place on the list. It sold 1.4 million copies last year just in the States, where it was released by independent Glassnote. Universal oversaw its release elsewhere.
Like Adele, the late Amy Winehouse and Florence + The Machine have two albums in the Top 10. Winehouse's showing comprises fifth-placed Lioness: Hidden Treasures, an Island-issued album of largely previously-unreleased material released posthumously last December, while her Grammy-winning 2006 album Back To Black is eighth after it returned to charts around the world following her death last July.
Fellow Island act Florence's second album Ceremonials, which was released last year, is in ninth place, while its 2009 predecessor Lungs is 10th. Both were big sellers in the US, Canada and Australia.
Syco signing Susan Boyle, who had the biggest-selling album overseas by a UK artist in both 2009 and 2010, is in sixth place this time thanks to her third album Someone To Watch Over Me, while Jessie J's debut album Who You Are is seventh.
Full analysis is in this week's Music Week alongside a chart of the biggest-selling singles last year overseas by UK acts.
