The story of the Pioneer GM maize crop has culminated in the biggest controversy on genetic modification (GM) issues in years. On Tuesday 11 February a record number of 19 EU countries declared themselves to be opposed to Pioneer's GM maize being authorised for cultivation in the EU. This included the Netherlands, Romania and Ireland, all of whom were expected to either vote in favour or abstain just before the vote. Only five countries said they were in favour (among them the UK, Spain and Sweden) and the rest abstained.
