17 Oct 2017 --- The so-called mega-merger planned between seed giants Bayer and US-based Monsanto should be blocked under EU competition law, according to a major new study from University College London. Released yesterday (October 16), on World Food Day, the authors of the report claim that the European Commission should be obliged to block the merger, which is currently under an in-depth investigation, even on a narrow reading of EU competition law.
