Singer Robbie Williams has sold the most albums in the UK so far this century - notching up sales of 6.3m. Coldplay are at number two, with sales of 6.2m albums, while solo singer Dido is in third place, with 5.7m albums.
The figures are based on albums sold in the UK from 1 January 2000 to 11 October 2005, but exclude greatest hits, live albums and downloads.
They were compiled by the Official UK Charts Company for C4 show The Biggest Selling Artists of the 21st Century.
Eminem and Westlife are fourth and fifth respectively, while the Top 10 is completed by Norah Jones, Blue, Anastacia, the Stereophonics and Oasis.
Kylie Minogue, Will Young and Craig David are just outside the Top 10.
Williams is currently number one in the UK album charts with his latest release, Intensive Care - his sixth solo studio album.
The 31-year-old first entered the chart as a solo artist in August 1996 with his cover of George Michael`s single Freedom.
He released his debut solo album, Life Thru A Lens, in October 1997. It was followed a year later by I`ve Been Expecting You.
Williams has released four more studio albums since then - Sing When You`re Winning (2000), Swing When You`re Winning (2001), Escapology (2002) and latest release Intensive Care.
He has also released a live album Live At Knebworth (2003) and a greatest hits collection (2004) but neither of these counted towards the millennium chart. The live album is the only one to date which failed to top the British album chart.
