The US Supreme Court has sided with the maker of Roundup weedkiller in a ruling that is expected to block thousands of lawsuits alleging it failed to warn people that the product could cause cancer.
The decision marks a significant victory for the agrochemical giant Bayer, which acquired Roundup when it bought its original manufacturer Monsanto in 2018, following a "tidal wave" of litigation that included multibillion-dollar verdicts against the company.
