The line-up for this summer’s Glastonbury festival has been leaked on the internet, two days before the full list of performers was due to be announced.

Music magazine NME’s website today boasted it had a “world exclusive” and listed the Raconteurs, Shakin’ Stevens and Panic At The Disco among the acts to play at the three-day Somerset festival.

According to the report, American hip-hop star Jay-Z will play the main Pyramid stage on Saturday night, with the American favourites Kings of Leon occupying the slot on Friday, and long-celebrated British band the Verve taking over on Sunday.

American act Panic at the Disco will headline The Other Stage on Friday, with Bristol innovators Massive Attack playing on Saturday, and dance Kings Groove Armada on Sunday.

Glastonbury organisers planned to announce the full line-up at midnight on Tuesday. They did not immediately return calls today.

The leak is the latest in a long line of misfortunes to befall this year’s event. Organisers have faced a barrage of criticism after choosing Jay-Z as the festival’s headliner.

High-profile musicians, including Oasis member Noel Gallagher, have asked why the festival has chosen a hip-hop act instead of continuing its rock tradition.

"If it ain't broke don't fix it. If you start to break it then people aren't going to go,” Gallagher complained.

“I'm sorry, but Jay-Z? No chance. Glastonbury has a tradition of guitar music and even when they throw the odd curve ball in on a Sunday night you go 'Kylie Minogue?' I don't know about it. But I'm not having hip-hop at Glastonbury. It's wrong."

Glastonbury founder Michael Eavis has defended the choice.

“Jay-Z is far from the first hip-hop artist to perform at Glastonbury, as one might assume from some strangely hysterical press reports."

While tickets have sold out within hours in previous years, this year sales were down.

After 37,500 tickets were left unpurchased, organisers were forced to reopen registration.
