Previously, London had already unilaterally extended the transition phase, while food imports from Great Britain to Northern Ireland are less controlled. The EU Commission reacted indignantly and announced legal steps.
Northern Ireland Protocol aims to prevent civil war from flaring up again
The aim of the laboriously negotiated Northern Ireland Protocol is to prevent border controls between the British province and the EU state Ireland – and thus new violence in the former civil war region. The Brexit agreement provides that Northern Ireland will continue to follow the EU rules on product standards and customs regulations. The result is a trade frontier within the UK. Imports from Great Britain to Northern Ireland must therefore be controlled and comply with EU requirements.
