Britney Spears's Blackout: 10 chart facts about the acclaimed album on its 10th anniversary

Ten years ago this week, Britney Spears released what would become her most critically acclaimed album to date: Blackout. 

Its chart success was almost inevitable - Britney had a strong track record on the charts, the album's lead single Gimme More had been a hit, and rarely a day passed when she wasn't been papped in the build up to its release during her much documented difficult year.

But its critical acclaim - Britney's first widespread praise for one of her records - came as a surprise to many, particularly given the months preceding its release. 

The likes of Rolling Stone, Pitchfork and The Guardian all praised the record's fresh and futuristic sound, The Times ranked it as the fifth best pop album of the decade, and in 2012 it was inducted into the Rock and Roll Hall of Fame library.  

To celebrate its tenth birthday, Official Charts presents ten essential #ChartFacts about how the album has performed in the UK. Could it be Britney's most underrated collection?
