Michael Eavis - the founder of the UK's biggest music extravaganza - has announced that he has almost certainly decided the prestigious event will look for a new home away from Worthy Farm in two years time and it may even go on tour in the future.

This year marks the 46th anniversary of Glastonbury Festival and the site has not only grown in popularity but also in size over four decades, now covering 900 acres of land.

It stretches outside of Michael's Worthy Farm and has slowly consumed the surrounding Somerset fields and it's thought that neighbouring land owners are unhappy with its huge size and impact on the environment, and that Michael has hit a brick wall negotiating renting their fields.

Speaking about his dilemma, the 80-year-old dairy farmer - who grew up on Worthy Farm - said he is reluctant to move the five-day festival but doesn't see what other choice he has.

Asked will Glastonbury Festival will relocate in the future he said it is "likely" to happen in 2018 and added to the Daily Mirror newspaper: "I'd stay, but it's getting complicated now."

Meanwhile, this year the world-famous event has attracted some of music's biggest acts for its headliners over the weekend in Muse, who perform on the Pyramid Stage on Friday, 24 June, Adele on Saturday 25 June, and Coldplay, who will draw the festival to a close on June 26.

Michael - who has passed on some of the management duties of Glastonbury to his daughter Emily Eavis - is very excited about this year's line-up.

He said previously: "We're going to announce the full line-up in April and it's the best line-up we've ever had."
