Glastonbury founder Michael Eavis has said that the festival might be forced to move in the future.

Eavis told Sky News that running festival at its current site is becoming increasingly complicated.

The farmer does not own the event’s entire site, where it has been since 1970. The site on which the Pyramid stage sits, at the centre of the festival, is owned by Eavis, but its surrounding areas are owned by others.

“I’m always worried about the future, about the land not being available because I only own the middle bit,” he said. “I may have to find a site that’s bigger and is all under the control of one person. That’s the ideal situation, so that might happen in the long-term,” he said.

More than 135,000 revellers pay hundreds of pounds to attend the festival, which this year includes headliners Kanye West, Florence & The Machine and Lionel Ritchie.

A move away from Worthy Farm has been cited as a risky decision, with many having spiritual and traditional attachments to the land.

Mr Eavis is looking into alternative sites, it was revealed, but he is keeping them secret and has yet to commit to a time frame. “All good things come to an end and one has to make changes. I would love it to stay but it’s getting very, very complicated now,” he said.
