On Monday the European Union announced that getting rid of the bloc's court oversight from the post-Brexit deal in relation to Ireland would remove ultimately remove Northern Ireland from the European market.
During a news conference, a commission spokesman said, "Our focus should be on those issues that matter the most to the people of Northern Ireland and not on requests such as removing the role of the European Court of Justice (ECJ),"
He added, "Doing this would effectively mean cutting Northern Ireland off from the EU's single market and related opportunities."
David Frost, the Brexit negotiator for Britain on Saturday published bits of the speak, set to publish later this week, reinforcing London's demand to scrap any position of power of the ECJ from the EU-UK agreement used to regulate the post-Brexit deal.
The commission stated that this week it would reveal its proposals to ease control over the trade coming from Northern Ireland to Ireland, but that they would not fundamentally sway from the current Brexit deal.
