Glastonbury has always been a political music festival. It started in 1970 as part of the hippie movement, has been associated with the Campaign for Nuclear Disarmament (CND) for more than 40 years, and is always haunted by Left-wing speakers who are guaranteed a rapturous welcome.

Causes championed at Worthy Farm over the years include saving the environment, world peace and lifting children out of poverty around the globe. This year, however, one issue overshadowed all others: the ongoing conflict in the Middle East.

The build-up to this year’s festival was dominated by questions about whether Kneecap, the Irish rappers, would remain on the bill or have their set broadcast by the BBC after one of their members was charged with a terror offence; it is alleged that Liam Óg Ó hAnnaidh displayed a Hezbollah flag at a concert last November. He denies the charges.
