There is no room for any changes to be made to the new Brexit deal, No 10 has indicated following the announcement of the “historic” agreement.
Asked if Rishi Sunak might return to Brussels to ask for any changes requested by the DUP, the prime minister’s official spokesperson said: “Certainly I think you heard the prime minister asked similar questions today. We think we have secured the right deal for all parties in Northern Ireland.
“We stand ready to have further talks with those parties if they have questions about how it works in practice, indeed, we did a great deal of that in the run up to this announcement.”
Mr Sunak travelled to Northern Ireland after securing a deal with the EU that he promised would be a “turning point” for the region after years of post-Brexit tensions.
The so-called Windsor Framework was earlier hailed as “historic” by the European Commission president, who insisted the deal marked a “new chapter” in UK-EU relations at a press conference with the prime minister.
