Planning for Glastonbury is one of the force's largest operations and lasts for 10 months of the year.

The police officer with overall control for policing at the festival attended the licence hearing and has regular contact with the festival organisers to ensure everyone is happy and conditions are met which will make everyone's job as easy as possible and lead to as few problems as possible.

During the planning process police will put into place a patrol plan, custody operation, CID teams, media and PR strategy, communications centre, traffic management plan and thorough links with their partner agencies including British Transport Police, Mendip District Council and organisers Glastonbury Festivals Ltd.

Everything from the number of police officers who will man the police post in the village of Pilton for the residents outside the festival to what diversions will be put in place should a crash happen on one of the B roads on the way to the site, is planned for.

Police start to move onto the site on Saturday, June 19, setting up the police compound near to the farmhouse at Worthy Farm on the festival site.

A senior officer will be on site at all times, running the whole police operation, 24 hours a day throughout the festival.

Officers are then deployed across the site to carry out general patrol, providing not only a reassuring presence to festival go-ers but also answering questions about anything and everything, from where to report a crime, where the Lost Vagueness is, and 'aren't your bullet-proof vests hot man?'

Officers on horseback, with dogs and on pedal cycles also patrol the site and the car parks to prevent and detect crime.

Undercover officers will be out around the site, focusing on drug dealers and potential criminals. We won't be telling you what these officers look like.

Back at the police compound there are the CID officers and the interview rooms where you can go to report a crime or be questioned about one you have committed. Also at the compound are the stables for the horses, the police command unit where decisions are made and most importantly, the food van.

There are also police operations related to the festival at the Bath and West Showground and back at police headquarters, Portishead. The cells for the naughty people are at Bath and West as well as Yeovil. The communications operation runs from police headquarters, Portishead with staff taking any 999 or non-emergency calls made from the festival and liasing with officers on site over enquiries to be made and work with other units.
