SCOTLAND’S biggest music festival will search fans for single-use vapes due to a ban.

TRNSMT will return to Glasgow Green this weekend, with Liam Gallagher, Gerry Cinnamon and Calvin Harris all set to headline.

The disposable vape ban was in place last year, but organisers have stepped up efforts to improve littering on the site.

Festival director Geoff Ellis said he hoped those who attend the three-day event "only leave footprints" when the site is packed up.

As well as single-use vapes, concertgoers will be banned from taking in flags, glass, and selfie sticks.

Ellis said: "It’s purely from a sustainability point of view in the same way that we’ve banned plastic on site as well.

"We try to do what we can in terms of sustainability and we try to encourage the audience to do the same."

CCTV and police detection dogs will be present at the entrance to the site and across the park.

Asked if he thought the single-use vape ban would be easy to enforce, he said: "Yes. I think it’s about communication.

"If you get the message out there to people, people listen. If you tell them not to bring stuff, they tend not to bring them.

"We’ve got a fairly rigorous searching system at the gate with the stewards anyway.”

Last year the Glastonbury Festival added single-use vapes to its list of things not to bring to the event.

In February, the Scottish Government confirmed plans to ban the electronic devices by next April due to health and environmental concerns.
