Plan B stormed to the top of the charts with his new album, film soundtrack Ill Manors.
The release, which features in the film of the same name, is the second number one album for the rapper, real name Ben Drew.
The east London-born artist has said the collection of songs were inspired by the issues surrounding the riots which broke out in the capital almost a year ago.
Plan B, real name Ben Drew, told NME the album confronted issues that had been "swept under the carpet"
He told NME earlier this week: "It's a mirror, a reflection of today. And of the problems that have been swept under the carpet since the riots put them on the front pages.
"That's why I made it so visceral, to get under people's skin. I wanted people to misunderstand it and to start debating it again."
This week's number two spot was also taken by a new release - Handwritten by American rockers The Gaslight Anthem while last week's number one, Good Morning To The Night, a collaboration between Elton John and Australian duo Pnau, dropped back to tenth place.
