Mrs May said the withdrawal deal was a “good deal for businesses and workers in the UK and in Northern Ireland”, but that she was working to get all parts of the UK a better deal.
“We have been talking to the European Union and discussing our options, because we both believe that the UK leaving the EU is going to have an impact on the border in Ireland.
“We have also been clear to the European Union that we would prefer to avoid that happening. But where the European Union offers no viable solution, the UK will remain committed to finding our own workable solution that avoids a hard border and continues to uphold the Belfast Agreement.”
The DUP have said they could vote against Mrs May’s Brexit deal if Mrs May pushes ahead with a “backstop” arrangement. The backstop plan would see the U.K. and the EU stay in a customs union to prevent a hard border.
DUP Westminster leader Nigel Dodds said the backstop remained the “unacceptable” option. He said: “We have had words from the Prime Minister, but words are words and you would have to be pretty naïve to think those are going to be put into effect.
“I think the level of expectations by Northern Ireland on the backstop, this is not my word, it is the word of others that this is unacceptable.”
“There are five options the Prime Minister has to focus on and the DUP will look at all of those. However, the backstop remains the unacceptable option.
He added: “The DUP are working and assessing all of those, but we also want to make sure we will look for the best solution for Northern Ireland and for the UK as a whole.”
