Bjork has pulled out of her headlining slot at the Wild In the Country Festival in Knebworth.

The Icelandic singer, who was due to perform next Saturday (July 5th), described the event as "volatile" and said she was “extremely disappointed” to have to withdraw.

"Organisers Geoff Oakes and Vince Power for Renaissance have been unable to secure any staging, sound and lighting for this festival making it impossible for the headline artists to perform and are unable to fulfill their contractual obligations to all of the artists contracted to perform at their event," a statement read.

Fans of the singer were also told to seek a refund from the point of purchase.

"We hope to be able to offer refunds to as many people as possible,” Mr Oakes is quoted as saying.
