DUP leader Sir Jeffrey Donaldson has said the party will need to see the legislation before agreeing to the Windsor Framework.
In a statement issued from Washington DC, he said: “We need to see the legislation, we need to ensure that what the Prime Minister is saying is translated into law and that the protection is robust and workable.
“I’m here to make plain what the unionist position is, why we have concerns and what we need to see happening to ensure we have strong stable foundations for our government in Northern Ireland."
