They have been added to the "what not to bring" section of the event's guidance list.

"Do not bring disposable vapes," the guidance reads. "They pollute the environment and can be hazardous at waste centres".

It is unclear whether they will be confiscated if found on people at the event.

The festival has long explored ways of promoting a sustainable future and protecting the environment.

Also on the list of what not to bring is any excess packaging and non-biodegradable body glitter.

"Please avoid the use of disposable wipes," the guidance says. "Wipes - even biodegradable wipes, which quickly breakdown into micro-plastics - are problematic environmental pollutants.

"Plant fibre-based biodegradable wipes release greenhouse gases when they decompose, so we would like people to really try to use alternatives. A washcloth and a bar of soap works wonders!"

The Glastonbury line-up also includes Lizzo, Christine And The Queens, Fatboy Slim, Lana Del Rey, Lewis Capaldi, Lil Nas X, Maneskin, Rudimental, Manic Street Preachers, The War On Drugs and Royal Blood.

But it's a mysterious act - set to play a prime-time slot on the main Pyramid Stage - that has got everyone talking.

Unknown band The ChurnUps are due to play the festival on the evening of Friday 23 June, ahead of Royal Blood and Arctic Monkeys.

Rock group Foo Fighters have fuelled speculation they may be behind the act following a cryptic note posted on social media this week by the band's lead singer Dave Grohl, who used the phrase "churning up" emotions.

Fans have suggested it is a hint at an upcoming appearance at Worthy Farm.
