Significant flooding has prompted the cancellation of the final day of the Creamfields dance music festival.
Torrential downpours have battered the UK on Saturday with up to an inch of rain falling in some places - and left the Cheshire site looking more like a swamp than a festival venue.
Anyone with a ticket for Sunday was told not to travel, while those already on site were urged to be patient while plans were put in place to allow them to leave safely.
Cheshire Police said extra public transport will be laid on.
In a statement, the organisers said: "It is with regret that today's event at Creamfields has been cancelled due to significant rainfall overnight and on-site flooding.
"Every effort has been made to continue with the event and following an evaluation of the site the decision has been made by the promoters, Cheshire Police and multi agencies on site to close today's final day in the interest of health and safety.
"The heavy downpour overnight has created issues across the site leaving many areas unusable.
"It is our primary concern at this time that assistance is given to those on site and ensure those campers exit safely."
The wet weather caused transport problems across the country and prompted the Environment Agency (EA) to issue a number of flood warnings and alerts.
