The court said Dewayne Johnson offered "abundant" evidence that glyphosate and other Roundup ingredients caused his cancer.

A California appeals court has refused to overturn a verdict in favour of a school caretaker who claimed the weedkiller Roundup caused his cancer.

Dewayne Johnson had been awarded $289.2m (£228.4m) in August 2018 after a San Francisco jury was told that the chemical was responsible for his non-Hodgkin's lymphoma.

The award was cut by the trial judge to $78.5m (£62m) and in the decision by the California appeals court this week, it was reduced further to $20.5m (£16.2m).
