The Voice coaches are back for a second series

Jessie J, Sir Tom Jones, Danny O'Donoghue and will be competing against each other on the BBC talent show, which is set to have some new twists this time round.

The show's ratings dropped during the first series following the end of the "swivel chair" rounds.

An 11-date tour featuring performances from the finalists was cancelled, due to poor ticket sales.

Leanne Mitchell, who was mentored by Sir Tom won the show last year, but a download version of her debut single failed to make it big in the charts.
