DUP Leader & First Minister of Northern Ireland Arlene Foster MLA said,
"This is an incredible act of hostility. By triggering Article 16 in this manner, the European Union has once again shown it is prepared to use Northern Ireland when it suits their interests but in the most despicable manner – over the provision of a vaccine which is designed to save lives.
At the first opportunity the EU has placed a hard border between Northern Ireland and the Republic of Ireland over the supply chain of the Coronavirus vaccine.
With the European Union using Article 16 in such an aggressive and most shameful way, it is now time for our Government to step up. I will be urging the Prime Minister to act and use robust measures including Article 16 to advance the interests of Northern Ireland and the rest of the United Kingdom."
