Emily Eavis has raised doubts about the future of the Glastonbury Festival.The daughter of Michael Eavis, who has helped her father to run the event for the past eight years, said that they had discussed the shelf life of the music festival at Christmas.

She said that they were treating the 38th festival this year, which will be headlined by Jay-Z, a rapper, as though it were the last.

Asked whether the event had a limited time span, she told Orange World, a mobile phone website: “Yeah, I probably do to be honest. We had a kind of retrospective time during Christmas, talking about it and whether it’s a long-term thing. I kinda feel that we should ply everything into this as if it could be the last. It’s a risky, risky business and it would be nice to think, to know that it could go on for ever [but] I don’t know if that’s possible.”

Mr Eavis, who founded the festival, said recently that Glastonbury had become too middle-aged and respectable. Last year fans bought 137,500 tickets in a record time of one hour and 45 minutes when they went on sale.

The first festival was held in 1970, a day after Jimi Hendrix died. Tickets costs £1, including milk from the farm.
