Mercury Prize boosts xx album sales
The xx's Mercury Prize success has boosted their album sales, but failed to propel them to the top of the chart.
The electronic trio's eponymous debut re-entered the top 10 but it was Brandon Flowers's Vertigo that took the top slot.
Over in the singles chart, X Factor winner Alexandra Burke leapt straight in at No 1.
The success of Start Without You, featuring American rapper Laza Morgan, meant Katy Perry was in second place for a second week.
It was a position she also held in the albums chart behind The Killers star Flowers.
Last week's No 1 single, Olly Murs's Please Don't Let Me Go dropped to fourth.
Amongst the notable new entrants in the top 40 were McFly.
The maturing boyband's Party Girl came in at No 6, making it the band's 15th top 10 single.
Three albums short-listed for the Mercury Prize - including the eventual winner - numbered amongst the top 10, with Biffy Clyro and Mumford And Sons joining The xx.
Mancunian band I Am Kloot also received a boost from the hype surrounding the annual award, with their nominated album Sky At Knight rising 53 places to 37.
