A controversial chemical will be allowed in the EU for another 10 years. After member states failed to reach an agreement amongst themselves, the European Commission decided that glyphosate, an agrichemical used in farming, will be re-authorised for a further decade.

There are also big environmental and wildlife dimensions to this debate, which continues in the member states and at the European Parliament. We delve into the issue with two MEPs.
