DUP Leader Arlene Foster MLA said,
“The United Kingdom voted to the leave the European Union as one nation and we are leaving as one nation.
Her Majesty’s Government have a clear understanding that the DUP will not countenance any arrangement that could lead to a new border being created in the Irish Sea. Indeed, the Prime Minister has been categorical on this matter in the House of Commons.
We are in constant contact on these issues with the Government and during our discussions, we reiterated that United Kingdom–Republic of Ireland arrangements may be necessary as we exit the EU but there can be no arrangements agreed that compromise the integrity of the UK single market and place barriers, real or perceived, to the free movement of goods, services and capital between Northern Ireland and the rest of the United Kingdom. We support the continuance of the Common Travel Area for the movement of people between the United Kingdom and the Republic of Ireland.
We will continue to work with the Government on the details of negotiations as they progress. We look forward to the European discussions being able to move to the second stage to deal with trading arrangements between the UK and the EU27.
As the EU exit discussions continue, there will be from time to time speculation, some of which is ill informed from those not across the details. For our part we remain focused on ensuring that as we leave the European Union we achieve an outcome that is beneficial to Northern Ireland and the United Kingdom as a whole. ”
