A farmer has spoken of his struggle to afford £40,000 to remove toxic waste from his land that has been dumped there by fly-tippers.

About 200 tonnes of rubbish was left on the Hertfordshire field last summer, but the person who did it has not been caught.

The farmer, who wishes to remain anonymous, said he risked being prosecuted over the mess, which includes asbestos, household and medical waste.

The Environment Agency said it did everything possible to ensure that those who dumped waste paid for the cost of removing it, but it becomes the landowner’s responsibility if that is not possible.
