Kendrick Lamar scores first U.K. number one album

Rapper Kendrick Lamar has replaced Sam Smith at the top of the U.K. albums chart with his sophomore album To Pimp A Butterfly.

The hip-hop star scores his first British chart-topper with the new release, knocking Smith's In The Lonely Hour into second place after racking up an eighth week at number one last week (ends15Mar15).

Dire Straits rocker Mark Knopfler's solo project Tracker is another new entry at three, while Van Morrison's Duets: Reworking The Catalog debuts at five, just behind Ed Sheeran's X.

Meanwhile, Smith retains the singles chart title with his John Legend collaboration Lay Me Down, which the duo recorded in aid of British charity Comic Relief.

King by Years & Years is another non-mover at two and Rihanna's FourFiveSeconds hit with Kanye West and Sir Paul McCartney moves up to three.
