A group of organisations working to end sewage pollution in the Thames is set to hold an event to amplify their voices later this month.

Oxford Clean Rivers Fest is scheduled for May 25 at Long Bridges Nature Park beside the Thames.

The event has been organised by the Oxfordshire Clean Rivers Initiative, which includes national charities River Action, Thames 21 and Earthwatch Europe.

The festival intends to celebrate the Thames' beauty while seeking action against sewage pollution.

It will feature music, entertainment, talks from speakers, and an opportunity to learn about the river and ways to contribute towards its restoration.

The event will run from midday to 6pm and will be free of charge.

James Wallace, CEO of River Action, said: "People all over Oxfordshire are unhappy and angry about the levels of sewage pollution in our rivers, including the rowers and swimmers who are supporting the event: we invite everyone to join us in saying no more talk - time for action."

Sasha Woods, director of science and policy at Earthwatch Europe, added: "This year is almost certain to be a general election year and we want to make sure that clean fresh water is top of the agenda for any new government.

"The data clearly shows that we are failing to look after our freshwater habitats and this festival is about calling for action to clean up our rivers so that they can thrive in future."
