JEREMY Corbyn is "happy" to speak to the organisers of the Glastonbury festival about his opposition to the use of zero-hours contracts, a senior spokesman for the Labour leader has said.

Mr Corbyn won a rapturous reception on-stage at this year's festival, with cheering crowds chanting his name to the tune of the White Stripes' Seven Nation Army.

But organisers including founder Michael Eavis have faced criticism over reports that hundreds of workers from across Europe hired on zero-hours contracts to clear up after the festival were laid off after just two days because there was not as much litter as expected.

The Labour leader has promised to ban zero-hours contracts and during his appearance on the Somerset festival's Pyramid Stage, he said young people should not have to "accept low wages and insecurity as just part of life".

Asked whether the row could lead Mr Corbyn to boycott the festival in future, the Labour spokesman said: "Jeremy and the Labour Party have take a very strong stand against the use of zero-hours contracts and the exploitation of migrant and other workers and we would take that view wherever it happened."

He added: "How Glastonbury runs its event and runs its finances is entirely a matter for them.

"But these contracts should not be in place and shouldn't be used.

"We oppose them and next time we are in Government we will ban them.".

Asked whether Mr Corbyn would raise the issue with organisers next time he visits the festival, the spokesman said: "He is happy to raise it right now.

"This kind of contract and these kinds of employment conditions are unacceptable."

In a statement, Glastonbury festival said: "In response to recent stories in the media, we would like to state that Glastonbury festival's post-event litter picking team are all given temporary worker agreements for the duration of the clean-up.

"As well as being paid, they are provided with free meals and access to on-site facilities.

"The length of the clean-up varies considerably from year to year, based largely upon the weather conditions before, during and after the festival.

"This is something the litter pickers - many of whom return year after year - are made aware of in their worker agreements (which assure them of a minimum of eight hours' work).

"This year was an unusually dry one for Glastonbury. That, coupled with a fantastic effort from festival goers in taking their belongings home, meant that the bulk of the litter picking work was completed after 2.5 days (in 2016, a very wet year, the equivalent period was around 10 days).

"All but a core crew of litter pickers were advised that there was no further work available after Friday (June 30). Those who weren't able to leave the site over the weekend were given further meals, plus assistance with travel to nearby towns with public transport links.

"We'd like to thank the litter pickers for their work on the clean-up, which was - as always - hugely valued by the festival."
