David Cameron was accused of undermining his wish to have young people vote in the EU referendum by choosing a date that was "terrible" for students because it clashed with Glastonbury.
On Thursday, the prime minister chose Exeter University as the venue to deliver a speech encouraging the young to vote in favour of EU membership at the referendum on June 23.
But one student not only tackled him over the choice of date and grilled him over his education policies.
"It's really nice to hear that, having raised my tuition fees by £9,000, you care about students," she said.
"I do wonder if now you put forward such a care, why is the referendum, which you have already argued is going to be more important to us on a date that is terrible for students, after we've had exams, there are graduations on that day, Glastonbury festival is on that day."
Cameron told her there was "no ideal" date for the referendum but that he wanted to hold it sooner rather than later so the campaign did not end up "taking over a whole year".
"We now have a postal voting system where it is very easy to apply for postal vote," he said. "Send that in and then to enjoy the Glastonbury festival."
Cameron added: "I always like watching it for the safety of my TV at home in front of a warm fire."
Some people suspicious of Cameron's claim he watches Glastonbury questioned why he needed a warm fire in the summer.

The 135,000 people due to attend this year’s Glastonbury could find themselves unable to vote in the referendum, which falls on 23 June.
As there will be no polling stations inside the site, organisers have urged people to register to vote, request a postal ballot or apply for someone back home to vote on their behalf instead.
People with tickets to the event were advised how to register to get a postal vote in an e-mail this week.
“On Thursday 23 June - the day after Glastonbury’s gates open - there will be a referendum on whether Britain should remain in the European Union. There will not be a polling station at the Festival, so we are strongly encouraging our ticket holders to register to vote by post or by proxy.
