Organizers of Glastonbury Festival have cleared a final, licensing hurdle.

The giant outdoor music event has been granted a four-year licence, beginning with this year's June 22-24 event.

Mendip District Council, which licenses the festival in Somerset, south west England, has given the festival the green light for a site capacity of 177,500, up from 150,000 in recent years.

The agreement represents the largest license in the United Kingdom, Melvin Benn, managing director of promoter and venues operator Mean Fiddler Music Group, tells Billboard.biz. Benn submitted the license on behalf of Mean Fiddler, which has handled Glastonbury's licensing and security since 2002.

"The whole process has gone extremely well this year thanks to excellent partnership working," comments Charles Uzzell, the council's business manager for planning and environment, in a statement issued today. "It has involved a lot of hard work from the applicant, the council and the responsible authorities, and the local community."

The allocation comprises 135,000 weekend tickets plus 5,000 Sunday-only tickets given to locals. The remainder is largely allocated to staff, artists and crew.

Weekend tickets will go on sale this Sunday, priced at £145 ($278), plus booking and postage fees. As part of a scheme to crack-down on scalpers, tickets will only be available to those 400,000 people who registered an application by March 5.

Although the bill has yet to be announced, Billboard.biz has learned that respective nightly headliners this year will be Arctic Monkeys, the Killers and the Who, with the Kaiser Chiefs, the Kooks and Kasabian taking second billing.

"The bands we've got are so good," founder Michael Eavis tells Billboard.biz, "it's amazing."

Under the terms of the license, the festival site is allowed to remain open for a maximum of six days. The dates proposed for this year are June 20 - 25. Music on the main stages, however, will be limited to the three core festival dates.
