Charlbury Riverside Festival postponed because of rain

About 5,000 people attended the festival over the weekend in 2011

A free music festival in Oxfordshire next weekend has been postponed because of concerns about flooding.

The Riverside Festival in Charlbury attracted about 5,000 people over the same weekend last year.

A spokesman said: "The risk of flooding has forced the organisers to postpone the event until later in the summer."

The Environment Agency has issued a flood alert for the River Thame and Chalgrove Brook, for the stretch from Marsworth to Dorchester.

It has advised people to be alert for disruption from possible flooding across parts of southern England.

There are amber warnings for Hampshire and Berkshire where between 20 and 60mm of rain is predicted.

In Wiltshire, Dorset and Oxfordshire yellow warnings have been issued with the potential of a month's rainfall in just a few hours.
