X Factor runner-up Olly Murs tops singles chart

Murs came second in last year's X Factor

Former X Factor contestant Olly Murs has gone straight to the top of the UK singles chart with his debut song Please Don't Let Me Go.

He beat Katy Perry's Teenage Dream into the number two spot while her album of the same name debuted at number one.

Last week's number one single Dynamite, by Taio Cruz, dropped to number three.

Pepper & Piano, a female duo from Sky1 talent show Must Be The Music, went straight into the chart at seven with You Took My Heart.

Speaking to the BBC News website, 26-year-old Murs put his popularity down to "the fact that I'm quite confident but I'm also an entertainer".

"I'm the same person in every single performance that I do," he said.

"I'm able to showcase my personality in my music so that's probably why people like me."

In the album chart, Mercury-nominated rock band Biffy Clyro climbed from number 27 to number three with Only Revolutions - one place behind last week's number one Recovery, by Eminem.

There were also new entries in the album chart for Man Alive, by Everything Everything, at 17, and Richard Thompson's Dream Attic, at number 20.
