James Blunt's debut album "Back To Bedlam" (Atlantic) is the biggest U.K. seller of the decade, according to the Official Charts Company.

Dido's debut "No Angel" (Arista/Sony Music Entertainment) is in second place on the decade chart followed by Amy Winehouse's sophomore 2006 set "Back to Black" (Island/Universal) at No. 3. "No Angel" was first released in 1999; the 2003 follow-up "Life For Rent" made No. 7 in the best-selling albums of the decade.

Leona Lewis' 2007 debut "Spirit" (Syco/Sony Music Entertainment) is at No. 4 in the decade chart, with David Gray's "White Ladder" (IHT/East West/Warner Music) from 1998 at No. 5.

"Not only was 'Back To Bedlam' a major phenomenon in 2005, it has continued selling for half a decade, which is testament to the power of the songs on the record and James' talents," said Max Lousada, chairman of Atlantic Records U.K., in a statement. "Everyone at Atlantic Records is extremely proud of what we've achieved together with James, and we're all looking forward to working with him on new material in 2010 and beyond."

Blunt was big in the UK, but only a One-Hit Wonder in the U.S.

"Back To Bedlam" did not reach the U.K. albums chart when it was first released in 2004 -- its first-week U.K. sale was 482. It eventually charted thanks to heavy radio rotation for the single "You're Beautiful" and moved more than 3.1 million copies in the U.K., according to 2008 OCC figures. Full details, including latest sales figures, of the U.K. albums and singles best-sellers of the decade will be issued by the Official Charts Company on Dec. 31.

The Beatles' "1" (Apple/EMI) compilation made No. 6 in the U.K. Scissor Sisters' self-titled debut, released by Polydor, made No. 9 -- the only foreign act in the top 10.

Coldplay's "A Rush Of Blood To The Head" (Parlophone/EMI) is at No. 8 and Take That's "Beautiful World" (Polydor/Universal) made No. 10.

The decade album chart was broadcast on national top 40 station BBC Radio 1 last night (Dec. 28).
