Glastonbury Festival has yet to start but has already been hit by severe traffic congestion, with people queuing in jams for up to eleven hours.

Festival organisers are urging any people yet to reach the site by car to abandon their journey and find "somewhere safe and warm" instead.

People arriving by coach or train were told to travel as planned but to be prepared for "your journey to take longer than usual".

The problems have been blamed on wet weather and ground conditions.

Festival goers arrive for the Glastonbury festival where heavy rain has caused isolated flooding and muddy fields.

A serious multi-vehicle crash on the A303 near Stonehenge this morning has added to the general congestion around the area.

Revellers from Yorkshire expressed their frustration on Twitter.

Two of the three festival car parks are reported to be closed adding to delays getting on to the rain-hit site.

The festival has not even yet begun, with the official entertainment for 175,000 ticket-holders beginning on Friday, June 24.
