Organisers add e-cigarettes to official ‘do not bring’ list, which also includes gazebos and knives

People heading to Glastonbury festival this month have been urged by organisers not to bring disposable vapes to the event.

The electronic devices simulate tobacco smoking, run on lithium batteries and are not rechargeable, meaning they are single-use products. Some estimates suggest about 1.3m are thrown away each week in the UK.
